Description

This update for compat-openssl098 fixes the following issues :

Security issue fixed:;

  • CVE-2015-3195: When presented with a malformed X509_ATTRIBUTE structure OpenSSL would leak memory. This structure is used by the PKCS#7 and CMS routines so any application which reads PKCS#7 or CMS data from untrusted sources is affected. SSL/TLS is not affected. (bsc#957812)

Non security issue fixed :

  • Prevent segfault in s_client with invalid options (bsc#952099)

Note that Tenable Network Security has extracted the preceding description block directly from the SUSE security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
