Problem description

Multiple vulnerabilities has been found and corrected in openssl:

The DTLS implementation in OpenSSL before 0.9.8s and 1.x before 1.0.0f
performs a MAC check only if certain padding is valid, which makes
it easier for remote attackers to recover plaintext via a padding
oracle attack (CVE-2011-4108).

Double free vulnerability in OpenSSL 0.9.8 before 0.9.8s, when
X509_V_FLAG_POLICY_CHECK is enabled, allows remote attackers to
have an unspecified impact by triggering failure of a policy check
(CVE-2011-4109).

The SSL 3.0 implementation in OpenSSL before 0.9.8s and 1.x before
1.0.0f does not properly initialize data structures for block cipher
padding, which might allow remote attackers to obtain sensitive
information by decrypting the padding data sent by an SSL peer
(CVE-2011-4576).

The Server Gated Cryptography (SGC) implementation in OpenSSL before
0.9.8s and 1.x before 1.0.0f does not properly handle handshake
restarts, which allows remote attackers to cause a denial of service
via unspecified vectors (CVE-2011-4619).

The GOST ENGINE in OpenSSL before 1.0.0f does not properly handle
invalid parameters for the GOST block cipher, which allows remote
attackers to cause a denial of service (daemon crash) via crafted
data from a TLS client (CVE-2012-0027).

The updated packages have been patched to correct these issues.
