This update for openssl fixes the following issues:
Security issues fixed:
- 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.
Please also note that we built the 13.2 openSUSE openssl already with
"no-ssl2".
* 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-2016-0702 aka the "CacheBleed" attack. (bsc#968050)
Various changes in the modular exponentation code were added that
make sure that it is not possible to recover RSA secret keys by
analyzing cache-bank conflicts on the Intel Sandy-Bridge microarchitecture.
Note that this was only exploitable if the malicious code was running
on the same hyper threaded Intel Sandy Bridge processor as the victim
thread performing decryptions.
- CVE-2016-0705 (bnc#968047):
A double free() bug in the DSA ASN1 parser code was fixed that could
be abused to facilitate a denial-of-service attack.
- 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-2016-0798 (bnc#968265)
The SRP user database lookup method SRP_VBASE_get_by_user() had a memory
leak that attackers could abuse to facility DoS attacks. To mitigate
the issue, the seed handling in SRP_VBASE_get_by_user() was disabled
even if the user has configured a seed. Applications are advised to
- We're unaffected by CVE-2016-0799 (boo#968374) because we use glibc's
printf implementation instead of the built in one
Bugs fixed:
- avoid running OPENSSL_config twice. This avoids breaking
engine loading. (boo#952871)
