22 |
+ |
bsdgrep now correctly handles -m to exclude only one file. |
23 |
+ |
|
24 |
+ |
UFS file systems can now be resized in read-write mode due to the new |
25 |
+ |
write suspension feature. |
26 |
+ |
|
27 |
+ |

28 |
+ |
|
29 |
+ |
GMIRROR & GRAID3 now mark volumes clean on shutdown earlier to help with ZFS issues. |

20160923: |
34 |
+ |
Security update for OpenSSL |
35 |
+ |
|
36 |
+ |
A malicious client can send an excessively large OCSP Status Request extension. |
37 |
+ |
If that client continually requests renegotiation, sending a large OCSP Status |
38 |
+ |
Request extension each time, then there will be unbounded memory growth on the |
39 |
+ |
server. [CVE-2016-6304] |
40 |
+ |
|
41 |
+ |
An overflow can occur in MDC2_Update() either if called directly or through |
42 |
+ |
the EVP_DigestUpdate() function using MDC2. If an attacker is able to supply |
43 |
+ |
very large amounts of input data after a previous call to EVP_EncryptUpdate() |
44 |
+ |
with a partial block then a length check can overflow resulting in a heap |
45 |
+ |
corruption. [CVE-2016-6303] |
46 |
+ |
|
47 |
+ |
If a server uses SHA512 for TLS session ticket HMAC it is vulnerable to a |
48 |
+ |
DoS attack where a malformed ticket will result in an OOB read which will |
49 |
+ |
ultimately crash. [CVE-2016-6302] |
50 |
+ |
|
51 |
+ |
The function BN_bn2dec() does not check the return value of BN_div_word(). |
52 |
+ |
This can cause an OOB write if an application uses this function with an |
53 |
+ |
overly large BIGNUM. This could be a problem if an overly large certificate |
54 |
+ |
or CRL is printed out from an untrusted source. TLS is not affected because |
55 |
+ |
record limits will reject an oversized certificate before it is parsed. |
56 |
+ |
[CVE-2016-2182] |
57 |
+ |
|
58 |
+ |
The function TS_OBJ_print_bio() misuses OBJ_obj2txt(): the return value is |
59 |
+ |
the total length the OID text representation would use and not the amount |
60 |
+ |
of data written. This will result in OOB reads when large OIDs are presented. |
61 |
+ |
[CVE-2016-2180] |
62 |
+ |
|
63 |
+ |
Some calculations of limits in OpenSSL have used undefined pointer arithmetic. |
64 |
+ |
This could cause problems with some malloc implementations. [CVE-2016-2177] |
65 |
+ |
|
66 |
+ |
Operations in the DSA signing algorithm should run in constant time in order to |
67 |
+ |
avoid side channel attacks. A flaw in the OpenSSL DSA implementation means that |
68 |
+ |
a non-constant time codepath is followed for certain operations. [CVE-2016-2178] |
69 |
+ |
|
70 |
+ |
In a DTLS connection where handshake messages are delivered out-of-order those |
71 |
+ |
messages that OpenSSL is not yet ready to process will be buffered for later |
72 |
+ |
use. Under certain circumstances, a flaw in the logic means that those messages |
73 |
+ |
do not get removed from the buffer even though the handshake has been completed. |
74 |
+ |
An attacker could force up to approx. 15 messages to remain in the buffer when |
75 |
+ |
they are no longer required. These messages will be cleared when the DTLS |
76 |
+ |
connection is closed. The default maximum size for a message is 100k. Therefore |
77 |
+ |
the attacker could force an additional 1500k to be consumed per connection. |
78 |
+ |
[CVE-2016-2179] |
79 |
+ |
|
80 |
+ |
A flaw in the DTLS replay attack protection mechanism means that records that |
81 |
+ |
arrive for future epochs update the replay protection "window" before the MAC |
82 |
+ |
for the record has been validated. This could be exploited by an attacker by |
83 |
+ |
sending a record for the next epoch (which does not have to decrypt or have a |
84 |
+ |
valid MAC), with a very large sequence number. This means that all subsequent |
85 |
+ |
legitimate packets are dropped causing a denial of service for a specific |
86 |
+ |
DTLS connection. [CVE-2016-2181] |
87 |
+ |
|
88 |
+ |
In OpenSSL 1.0.2 and earlier some missing message length checks can result in |
89 |
+ |
OOB reads of up to 2 bytes beyond an allocated buffer. There is a theoretical |
90 |
+ |
DoS risk but this has not been observed in practice on common platforms. |
91 |
+ |
[CVE-2016-6306] |
92 |
+ |
|
93 |
+ |
20160918: |
94 |
+ |
With the addition of auditdistd(8), a new auditdistd user is now |
95 |
+ |
depended on during installworld. "mergemaster -p" can be used to add |
96 |
+ |
the user prior to installworld. |
97 |
+ |
|
98 |
+ |
The VFS KBI was changed with the merge of several nullfs |
99 |
+ |
optimizations and fixes. All filesystem modules must be |
100 |
+ |
recompiled. |
101 |
+ |
|
102 |
+ |
20160916: |
103 |
+ |
The random(4) support for the VIA hardware random number |
104 |
+ |
generator (`PADLOCK') is no longer enabled unconditionally. |
105 |
+ |
Add the PADLOCK_RNG option in the custom kernel config if |
106 |
+ |
needed. The GENERIC kernels on i386 and amd64 do include the |
107 |
+ |
option, so the change only affects the custom kernel |
108 |
+ |
configurations. |
109 |
+ |
|
110 |
+ |
A new version of ZFS (pool version 5000) has been merged. |
111 |
+ |
Starting with this version the old system of ZFS pool versioning |
112 |
+ |
is superseded by "feature flags". This concept enables forward |
113 |
+ |
compatibility against certain future changes in functionality of ZFS |
114 |
+ |
pools. The first two read-only compatible "feature flags" for ZFS |
115 |
+ |
pools are "com.delphix:async_destroy" and "com.delphix:empty_bpobj". |
116 |
+ |
For more information read the new zpool-features(7) manual page. |
117 |
+ |
Please refer to the "ZFS notes" section of this file for information |
118 |
+ |
on upgrading boot ZFS pools. |
119 |
+ |
|
120 |
+ |
20160906: |
121 |
+ |
Add support for the MosChip MCS9904 four serial ports |
122 |
+ |
controller. |
123 |
+ |
|
124 |
+ |
Add support for walltimestamp in DTrace. |
125 |
+ |
|
126 |
+ |
Various gdb improvments. |
127 |
+ |
|
128 |
+ |
ZFS |
129 |
+ |
Import the zio nop-write improvement from Illumos. To reduce I/O, |
130 |
+ |
nop-write omits overwriting data if the checksum (cryptographically |
131 |
+ |
secure) of new data matches the checksum of existing data. |
132 |
+ |
It also saves space if snapshots are in use. |
133 |
+ |
|
134 |
+ |
It currently works only on datasets with enabled compression, disabled |
135 |
+ |
deduplication and sha256 checksums. |
136 |
+ |
|
137 |
+ |
Add loader(8) tunable to enable/disable nopwrite functionality: |
138 |
+ |
vfs.zfs.nopwrite_enabled |
139 |
+ |
|
140 |
+ |
Introduce a new dataset aclmode setting "restricted" to protect ACL's |
141 |
+ |
being destroyed or corrupted by a drive-by chmod. |
142 |
+ |
|
143 |
+ |
New loader-only tunables: |
144 |
+ |
vfs.zfs.sync_pass_deferred_free |
145 |
+ |
vfs.zfs.sync_pass_dont_compress |
146 |
+ |
vfs.zfs.sync_pass_rewrite |
147 |
+ |
|
148 |
+ |

149 |
+ |
|
150 |
+ |
Fix problem with the Samsung 840 PRO series SSD detection. |
151 |
+ |
The device reports support for SATA Asynchronous Notification in its |
152 |
+ |
IDENTIFY data, but returns error on attempt to enable that feature. |
153 |
+ |
Make SATA XPT of CAM only report these errors, but not fail the device. |
154 |
+ |
|
155 |
+ |
20160905: |
156 |
+ |
Add a resource limit for the total number of kqueues |
157 |
+ |
available to the user. Kqueue now saves the ucred of the |
158 |
+ |
allocating thread, to correctly decrement the counter on close. |
159 |
+ |
Based on FreeBSD SVN 256849 |

OpenSSL security patch |
228 |
+ |
|
229 |
+ |
The padding check in AES-NI CBC MAC was rewritten to be in constant time |
230 |
+ |
by making sure that always the same bytes are read and compared against |
231 |
+ |
either the MAC or padding bytes. But it no longer checked that there was |
232 |
+ |
enough data to have both the MAC and padding bytes. [CVE-2016-2107] |
233 |
+ |
|
234 |

|
237 |
+ |
An overflow can occur in the EVP_EncryptUpdate() function, however it is |
238 |
+ |
believed that there can be no overflows in internal code due to this problem. |
239 |
+ |
[CVE-2016-2106] |
240 |
+ |
|
241 |
+ |
When ASN.1 data is read from a BIO using functions such as d2i_CMS_bio() |
242 |
+ |
a short invalid encoding can casuse allocation of large amounts of memory |
243 |
+ |
potentially consuming excessive resources or exhausting memory. |
