Problem Description:

A vulnerability has been found and corrected in openssl:

Double free vulnerability in the ssl3_get_key_exchange function in
the OpenSSL client (ssl/s3_clnt.c) in OpenSSL 1.0.0a, 0.9.8, 0.9.7,
and possibly other versions, when using ECDH, allows context-dependent
attackers to cause a denial of service (crash) and possibly execute
arbitrary code via a crafted private key with an invalid prime. NOTE:
some sources refer to this as a use-after-free issue (CVE-2010-2939).

The updated packages have been patched to correct this issue.
