   An update that contains security fixes can now be installed.

Description:


   OpenSSL has been updated to fix various security issues:

       *

         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.
