 Mandriva Linux Security Advisory                         MDVSA-2012:007
 http://www.mandriva.com/security/
 _______________________________________________________________________

 Package : openssl
 Date    : January 16, 2012
 Affected: 2011.
 _______________________________________________________________________

 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.
