# Line 1 | Line 1
1   Updating Information for MidnightBSD users.
2  
3 + 20160814:
4 +        switched default desktop port to midnightbsd-desktop. This gives us flexibility to change it
5 +        in the release after the fact.
6 +
7 + 20160811:
8 +        libdispatch 210
9 +
10 +        Added quirks for several models of SSDs to enable advanced format/4k mode. List includes
11 +        Samsung 830, 840, 850 and 750 series, Intel x25 and a few Toshiba models. Also
12 +        added WD Red drives.
13 +
14 +        Updated list of pci device vendors.
15 +
16 +        Updated list of usb devices.
17 +
18 + 20160807:
19 +        Implement several changes to libmport to fix some memory corruption issues.
20 +
21 + 20160806:
22 +        sqlite3 3.13.0
23 +
24 + 20160805:
25 +        Merged fixes for libmport that improve error handling when installing packages. Also
26 +        support mkdir -p like behavior for plist entries.
27 +
28 + 20160531:
29 +        Fix four security issues with MidnightBSD.
30 +
31 +        The implementation of TIOCGSERIAL ioctl(2) does not clear the output
32 +        struct before sending to userland in the linux emulation layer.
33 +
34 +        The compat 43 stat(2) system call exposes kernel stack to userland.
35 +
36 +        libarchive - CVE-2015-2304 and CVE-2013-0211 fix issues with
37 +        cpio directory traversal and an integer signedness error in the archive
38 +        write zip data routine.
39 +
40 +
41 + 20160528:
42 +        Fixed minor issues with mined(1) and msearch(1).
43 +
44 + 20160526:
45 +        Add support for Ivybridge and Haswell Intel CPUs to hwpmc(4).
46 +
47 +        Fix libpmc(3) build with clang compiler.
48 +
49 + 20160519:
50 +        Kernel Security updates
51 +
52 +        atkbd(4) - Incorrect signedness comparison in the ioctl(2) handler allows a malicious
53 +        local user to overwrite a portion of the kernel memory.
54 +
55 +        Incorrect argument handling in sendmsg(2)
56 +
57 +        Incorrect argument handling in the socket code allows malicious local
58 +        user to overwrite large portion of the kernel memory.
59 +
60 + 20160505:
61 +        OpenSSL security patch
62 +
63 +        The padding check in AES-NI CBC MAC was rewritten to be in constant time
64 +        by making sure that always the same bytes are read and compared against
65 +        either the MAC or padding bytes. But it no longer checked that there was
66 +        enough data to have both the MAC and padding bytes. [CVE-2016-2107]
67 +
68 +        An overflow can occur in the EVP_EncodeUpdate() function which is used for
69 +        Base64 encoding of binary data. [CVE-2016-2105]
70 +
71 +        An overflow can occur in the EVP_EncryptUpdate() function, however it is
72 +        believed that there can be no overflows in internal code due to this problem.
73 +        [CVE-2016-2106]
74 +
75 +        When ASN.1 data is read from a BIO using functions such as d2i_CMS_bio()
76 +        a short invalid encoding can casuse allocation of large amounts of memory
77 +        potentially consuming excessive resources or exhausting memory.
78 +        [CVE-2016-2109]
79 +
80 + 20160412:
81 +        0.8 stable branch created. Continue development as 0.9.
82 +
83 +        Fix several issues with wait6 system call addition.
84 +
85 + 20160409:
86 +        libmport now supports two new plist formats:
87 +        @(root,wheel,4775) myfile
88 +        @dir(root,wheel,775) mydir
89 +
90 +        On delete, absoluate paths are now handled properly.
91 +
92 + 20160317:
93 +        OpenSSH doesn't have the luck of the Irish.
94 +
95 +        Fix a security issue with OpenSSH X11 forwarding that can allow an attacker
96 +        run shell commands on the call to xauth.
97 +
98 +        Incorrect argument validation in sysarch(2)
99 +
100 +        A special combination of sysarch(2) arguments, specify a request to
101 +        uninstall a set of descriptors from the LDT.  The start descriptor
102 +        is cleared and the number of descriptors are provided.  Due to invalid
103 +        use of a signed intermediate value in the bounds checking during argument
104 +        validity verification, unbound zero'ing of the process LDT and adjacent
105 +        memory can be initiated from usermode.
106 +
107 +        Patch obtained from FreeBSD.
108 +
109 + 20160229:
110 +        top now displays information on ZFS arc cache.
111 +
112 + 20160228:
113 +        llvm + clang 3.3 is now the default compiler in MidnightBSD.
114 +
115 + 20160222:
116 +        Introduce pipe2 to linux emulation layer.
117 +
118 + 20160114:
119 +        OpenSSL
120 +
121 +        The signature verification routines will crash with a NULL pointer dereference
122 +        if presented with an ASN.1 signature using the RSA PSS algorithm and absent
123 +        mask generation function parameter. [CVE-2015-3194]
124 +
125 +        When presented with a malformed X509_ATTRIBUTE structure, OpenSSL will leak
126 +        memory. [CVE-2015-3195]
127 +
128 +        If PSK identity hints are received by a multi-threaded client then the values
129 +        are incorrectly updated in the parent SSL_CTX structure.  [CVE-2015-3196]
130 +
131 +        Fix security on bsnmpd configuration file during installation.
132 +
133 +        TCP MD5 signature denial of service
134 +
135 +        A programming error in processing a TCP connection with both TCP_MD5SIG
136 +        and TCP_NOOPT socket options may lead to kernel crash.
137 +
138 +        SCTP
139 +
140 +        A lack of proper input checks in the ICMPv6 processing in the SCTP stack
141 +        can lead to either a failed kernel assertion or to a NULL pointer
142 +        dereference.  In either case, a kernel panic will follow.
143 +
144 + 20160102:
145 +        Happy New Year
146 +
147 + 20151101:
148 +        Increase kern.ipc.somaxconn default to 256.
149 +
150 + 20151017:
151 +        Add initial statistics api to libmport and a driver to print
152 +        it in mport(1).
153 +
154 + 20151002:
155 +        Revised rpcbind(8) patch to fix issues with NIS
156 +
157 + 20150930:
158 +        In rpcbind(8), netbuf structures are copied directly, which would result in
159 +        two netbuf structures that reference to one shared address buffer.  When one
160 +        of the two netbuf structures is freed, access to the other netbuf structure
161 +        would result in an undefined result that may crash the rpcbind(8) daemon.
162 +
163 + 20150926:
164 +        libmport now supports @preexec, @postexec, @preunexec and @postunexec
165 +        to replace @exec and @unexec.  
166 +
167 +        pre exec runs afer pre-install scripts but before actual installation
168 +
169 +        post exec runs after install but before post install scripts and
170 +        pkg message.
171 +
172 +        pre unexec runs before pre uninstall scripts
173 +
174 +        post unexec runs before de-install scripts and after file removal.
175 +
176 + 20150917:
177 +        Fix kqueue write events for files > 2GB
178 +
179 + 20150825:
180 +        kernel:
181 +        fix a security issue on amd64 where the GS segment CPU register can be changed via
182 +        userland value in kernel mode by using an IRET with #SS or #NP exceptions.
183 +
184 +        openssh:
185 +        A programming error in the privileged monitor process of the sshd(8)
186 +        service may allow the username of an already-authenticated user to be
187 +        overwritten by the unprivileged child process.
188 +
189 +        A use-after-free error in the privileged monitor process of he sshd(8)
190 +        service may be deterministically triggered by the actions of a
191 +        compromised unprivileged child process.
192 +
193 +        A use-after-free error in the session multiplexing code in the sshd(8)
194 +        service may result in unintended termination of the connection.
195 +
196 + 20150818:
197 +        expat security fix
198 +
199 + 20150815:
200 +        libc changes:
201 +        setmode(3) now returns errno consistently on error.
202 +        libc will compile without error using clang
203 +
204 + 20150814:
205 +        wait6 system call added.
206 +
207 +        date(1) now handles non numeric numbers passed to -r
208 +        like GNU coreutils for improved compatibility.
209 +
210 + 20150811:
211 +        ata(4) AMD Hudson2 SATA controller support.
212 +        Intel lynxpoint SATA.
213 +
214 +        Fix some const warnings when building several device drivers
215 +        with llvm/clang.
216 +
217 +        Sync cas(4) with FreeBSD 9-stable.
218 +
219 +        Fix some minor issues with ath(4).
220 +
221 + 20150809:
222 +        xz 5.0.8
223 +
224 + 20150808:
225 +        libmport now logs installation and removal of packages to syslog.
226 +
227 + 20150805:
228 +        routed - fix a potential security issue where traffic from outside
229 +        the network can disrupt routing.
230 +
231 +        bsd patch - fix a bug with ed(1) scripts allowing unsanitized input
232 +        to run.
233 +
234 + 20150802:
235 +        jansson 2.7 library added. (libjansson is a JSON library in C)
236 +
237 + 20150728:
238 +        Heimdal 1.5.2 (kerberos implementation)
239 +
240 +        OpenSSL 1.0.1o
241 +
242 +        cpucontrol(8) now supports VIA CPUs. Synced with FreeBSD 9.2.
243 +
244 +        TCP Resassemly resource exhaustion bug:
245 +        There is a mistake with the introduction of VNET, which converted the
246 +        global limit on the number of segments that could belong to reassembly
247 +        queues into a per-VNET limit.  Because mbufs are allocated from a
248 +        global pool, in the presence of a sufficient number of VNETs, the
249 +        total number of mbufs attached to reassembly queues can grow to the
250 +        total number of mbufs in the system, at which point all network
251 +        traffic would cease.
252 +        Obtained from: FreeBSD 8
253 +
254 +        OpenSSH
255 +
256 +        Fix two security vulnerabilities:
257 +        OpenSSH clients does not correctly verify DNS SSHFP records when a server
258 +        offers a certificate. [CVE-2014-2653]
259 +
260 +        OpenSSH servers which are configured to allow password authentication
261 +        using PAM (default) would allow many password attempts. A bug allows
262 +        MaxAuthTries to be bypassed. [CVE-2015-5600]
263 +
264 +
265 +        Switch to bsdpatch (from FreeBSD & OpenBSD)
266 +
267 + 20150726:
268 +        BSD Sort updated
269 +
270 +        sqlite 3.8.10.2
271 +
272 + 20150725:
273 +        Import reallocarray from OpenBSD's libc.  
274 +
275 +        The reallocarray() function is similar to realloc() except it operates on
276 +        nmemb members of size size and checks for integer overflow in the
277 +        calculation nmemb * size.
278 +
279 + 20150722:
280 +        Fix a bug where TCP connections transitioning to LAST_ACK
281 +        state can get stuck. This can result in a denial of service.
282 +
283 + 20150715:
284 +        libmport now supports @shell and @sample in plists. This means that
285 +        a shell port can automatically add an entry to /etc/shells and remove
286 +        it upon uninstallation. For sample files, a copy is made without the
287 +        .sample extension if one does not exist and it is removed automatically
288 +        only if the md5 hash of the two files is the same.
289 +
290 + 20150709:
291 +        flex 2.5.39
292 +
293 + 20150702:
294 +        ZFS in MidnightBSD now supports lz4 compression. You can enable it
295 +        with zfs set compression=lz4 pool/path.
296 +
297 +        Verify it's working with
298 +        zfs get compressratio pool/path
299 +        du -h -s *
300 +
301 +        Note you must write new data when turning on compression to see
302 +        changes. Existing files are not compressed.
303 +
304 +        Note: While we used the same basic implementation of lz4 that
305 +        FreeBSD and OpenZFS uses, we did not yet implement features support
306 +        and the zfs version still reports 28. This may come in a future update
307 +        to ZFS.
308 +
309 + 20150621:
310 +        libmport now automatically stops services when deleting packages.
311 +
312 +        The package must have installed an rc.d script in /usr/local/etc
313 +        for this to work. This is equivalent to running service <name> onestop
314 +
315 + 20150618:
316 +        Sendmail
317 +
318 +        With the recent changes to OpenSSL to block 512 bit certificates,
319 +        sendmail can't connect with TLS to some servers.
320 +
321 +        Increase the default size to 1024 bit for client connections to
322 +        match the server configuration.
323 +
324 +        ZFS
325 +
326 +        Added ZFS TRIM support which is enabled by default. To disable
327 +        ZFS TRIM support set vfs.zfs.trim.enabled=0 in loader.conf.
328 +
329 +        Creating new ZFS pools and adding new devices to existing pools
330 +        first performs a full device level TRIM which can take a significant
331 +        amount of time. The sysctl vfs.zfs.vdev.trim_on_init can be set to 0
332 +        to disable this behaviour.
333 +
334 +        ZFS TRIM requires the underlying device support BIO_DELETE which
335 +        is currently provided by methods such as ATA TRIM and SCSI UNMAP
336 +        via CAM, which are typically supported by SSD's.
337 +
338 +        Stats for ZFS TRIM can be monitored by looking at the sysctl's
339 +        under kstat.zfs.misc.zio_trim.
340 +
341 +        rc.d
342 +
343 +        Reworked handling of cleanvar and FILESYSTEMS so that FILESYSTEMS
344 +        implies everything is mounted and ready to go.
345 +
346 +        Changed how ip6addressctl maps IPv6 on startup.
347 +
348 + 20150613:
349 +        tzdata 2015d
350 +
351 + 20150612:
352 +        OpenSSL 0.9.8zg
353 +
354 + 20150419:
355 +        MidnightBSD 0.6 stable branch created. Continue 0.7
356 +        development.
357 +
358 + 20150418:
359 +        sqlite 3.8.9
360 +
361 + 20150407:
362 +        Fix two security vulnerabilities:
363 +
364 +        The previous fix for IGMP had an overflow issue. This has been corrected.
365 +
366 +        ipv6: The Neighbor Discover Protocol allows a local router to advertise a
367 +        suggested Current Hop Limit value of a link, which will replace
368 +        Current Hop Limit on an interface connected to the link on the MidnightBSD
369 +        system.
370 +
371 + 20150319:
372 +        OpenSSL 0.9.8.zf
373 +
374 +        mksh R50e
375 +
376 +        Apple mDNSResponder 561.1.1
377 +
378 + 20150306:
379 +        Upgrade OpenSSL to 0.9.8ze
380 +
381 + 20150225:
382 +        Fix two security vulnerabilities.
383 +
384 +        1. BIND servers which are configured to perform DNSSEC validation and which
385 +        are using managed keys (which occurs implicitly when using
386 +        "dnssec-validation auto;" or "dnssec-lookaside auto;") may exhibit
387 +        unpredictable behavior due to the use of an improperly initialized
388 +        variable.
389 +
390 +        CVE-2015-1349
391 +
392 +        2. An integer overflow in computing the size of IGMPv3 data buffer can result
393 +        in a buffer which is too small for the requested operation.
394 +
395 +        This can result in a DOS attack.
396 +
397 + 20141211:
398 +        Fix a security issue with file and libmagic that can allow
399 +        an attacker to create a denial of service attack on any
400 +        program that uses libmagic.
401 +
402 + 20141109:
403 +        Fix building perl during buildworld when the GDBM port is installed.
404 +
405 + 20141106:
406 +        tzdata 2014i
407 +
408 + 20141102:
409 +        serf 1.3.8
410 +
411 + 20141031:
412 +        tnftp 20141031 fixes a security vulnerability with tnftp,
413 +        CVE-2014-8517.
414 +
415 + 20141028:
416 +        OpenSSL 0.9.8zc
417 +
418 + 20141021:
419 +        Fix several security vulnerabilities in routed, rtsold,
420 +        and namei with respect to Capsicum sandboxes looking up
421 +        nonexistent path names and leaking memory.
422 +
423 +        The input path in routed(8) will accept queries from any source and
424 +        attempt to answer them.  However, the output path assumes that the
425 +        destination address for the response is on a directly connected
426 +        network.
427 +
428 +        Due to a missing length check in the code that handles DNS parameters,
429 +        a malformed router advertisement message can result in a stack buffer
430 +        overflow in rtsold(8).
431 +
432   20141011:
433          mksh R50d - fix field splitting regression and null
