This update for libopenssl0_9_8 fixes the following issues :
CVE-2016-0800 aka the ‘DROWN’ attack (bsc#968046):
OpenSSL was vulnerable to a cross-protocol attack that could lead to decryption of TLS sessions by using a server supporting SSLv2 and EXPORT cipher suites as a Bleichenbacher RSA padding oracle.
This update changes the openssl library to :
Disable SSLv2 protocol support by default.
This can be overridden by setting the environment variable ‘OPENSSL_ALLOW_SSL2’ or by using SSL_CTX_clear_options using the SSL_OP_NO_SSLv2 flag.
Note that various services and clients had already disabled SSL protocol 2 by default previously.
Disable all weak EXPORT ciphers by default. These can be reenabled if required by old legacy software using the environment variable ‘OPENSSL_ALLOW_EXPORT’.
CVE-2016-0797 (bnc#968048): The BN_hex2bn() and BN_dec2bn() functions had a bug that could result in an attempt to de-reference a NULL pointer leading to crashes. This could have security consequences if these functions were ever called by user applications with large untrusted hex/decimal data. Also, internal usage of these functions in OpenSSL uses data from config files or application command line arguments. If user developed applications generated config file data based on untrusted data, then this could have had security consequences as well.
CVE-2016-0799 (bnc#968374) On many 64 bit systems, the internal fmtstr() and doapr_outch() functions could miscalculate the length of a string and attempt to access out-of-bounds memory locations. These problems could have enabled attacks where large amounts of untrusted data is passed to the BIO_*printf functions.
If applications use these functions in this way then they could have been vulnerable. OpenSSL itself uses these functions when printing out human-readable dumps of ASN.1 data. Therefore applications that print this data could have been vulnerable if the data is from untrusted sources. OpenSSL command line applications could also have been vulnerable when they print out ASN.1 data, or if untrusted data is passed as command line arguments. Libssl is not considered directly vulnerable.
The package was updated to 0.9.8zh :
fixes many security vulnerabilities (not separately listed): CVE-2015-3195, CVE-2015-1788, CVE-2015-1789, CVE-2015-1790, CVE-2015-1792, CVE-2015-1791, CVE-2015-0286, CVE-2015-0287, CVE-2015-0289, CVE-2015-0293, CVE-2015-0209, CVE-2015-0288, CVE-2014-3571, CVE-2014-3569, CVE-2014-3572, CVE-2015-0204, CVE-2014-8275, CVE-2014-3570, CVE-2014-3567, CVE-2014-3568, CVE-2014-3566, CVE-2014-3510, CVE-2014-3507, CVE-2014-3506, CVE-2014-3505, CVE-2014-3508, CVE-2014-0224, CVE-2014-0221, CVE-2014-0195, CVE-2014-3470, CVE-2014-0076, CVE-2013-0169, CVE-2013-0166
