7462 (8 years ago) by laffer1: Security patch OpenSSL for DROWN A cross-protocol attack was discovered that could lead to decryption of TLS sessions by using a server supporting SSLv2 and EXPORT cipher suites as a Bleichenbacher RSA padding oracle. Note that traffic between clients and non-vulnerable servers can be decrypted provided another server supporting SSLv2 and EXPORT ciphers (even with a different protocol such as SMTP, IMAP or POP3) shares the RSA keys of the non-vulnerable server. This vulnerability is known as DROWN. [CVE-2016-0800] A double free bug was discovered when OpenSSL parses malformed DSA private keys and could lead to a DoS attack or memory corruption for applications that receive DSA private keys from untrusted sources. This scenario is considered rare. [CVE-2016-0705] The SRP user database lookup method SRP_VBASE_get_by_user had confusing memory management semantics; the returned pointer was sometimes newly allocated, and sometimes owned by the callee. The calling code has no way of distinguishing these two cases. [CVE-2016-0798] In the BN_hex2bn function, the number of hex digits is calculated using an int value |i|. Later |bn_expand| is called with a value of |i * 4|. For large values of |i| this can result in |bn_expand| not allocating any memory because |i * 4| is negative. This can leave the internal BIGNUM data field as NULL leading to a subsequent NULL pointer dereference. For very large values of |i|, the calculation |i * 4| could be a positive value smaller than |i|. In this case memory is allocated to the internal BIGNUM data field, but it is insufficiently sized leading to heap corruption. A similar issue exists in BN_dec2bn. This could have security consequences if BN_hex2bn/BN_dec2bn is ever called by user applications with very large untrusted hex/dec data. This is anticipated to be a rare occurrence. [CVE-2016-0797] The internal |fmtstr| function used in processing a "%s" formatted string in the BIO_*printf functions could overflow while calculating the length of a string and cause an out-of-bounds read when printing very long strings. [CVE-2016-0799] A side-channel attack was found which makes use of cache-bank conflicts on the Intel Sandy-Bridge microarchitecture which could lead to the recovery of RSA keys. [CVE-2016-0702] s2_srvr.c did not enforce that clear-key-length is 0 for non-export ciphers. If clear-key bytes are present for these ciphers, they displace encrypted-key bytes. [CVE-2016-0703] s2_srvr.c overwrites the wrong bytes in the master key when applying Bleichenbacher protection for export cipher suites. [CVE-2016-0704] Obtained from: OpenSSL & FreeBSD |
