"OpenSSL was updated to fix various security issues.

Following security issues were fixed :

  - CVE-2015-0209: A Use After Free following
    d2i_ECPrivatekey error was fixed which could lead to
    crashes for attacker supplied Elliptic Curve keys. This
    could be exploited over SSL connections with client
    supplied keys.

  - CVE-2015-0286: A segmentation fault in ASN1_TYPE_cmp was
    fixed that could be exploited by attackers when e.g.
    client authentication is used. This could be exploited
    over SSL connections.

  - CVE-2015-0287: A ASN.1 structure reuse memory corruption
    was fixed. This problem can not be exploited over
    regular SSL connections, only if specific client
    programs use specific ASN.1 routines.

  - CVE-2015-0288: A X509_to_X509_REQ NULL pointer
    dereference was fixed, which could lead to crashes. This
    function is not commonly used, and not reachable over
    SSL methods.

  - CVE-2015-0289: Several PKCS7 NULL pointer dereferences
    were fixed, which could lead to crashes of programs
    using the PKCS7 APIs. The SSL apis do not use those by
    default.

  - CVE-2015-0292: Various issues in base64 decoding were
    fixed, which could lead to crashes with memory
    corruption, for instance by using attacker supplied PEM
    data.

  - CVE-2015-0293: Denial of service via reachable assert in
    SSLv2 servers, could be used by remote attackers to
    terminate the server process. Note that this requires
    SSLv2 being allowed, which is not the default.

  - CVE-2009-5146: A memory leak in the TLS hostname
    extension was fixed, which could be used by remote
    attackers to run SSL services out of memory.

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."
