 Mandriva Linux Security Advisory                         MDVSA-2013:052
 http://www.mandriva.com/en/support/security/
 _______________________________________________________________________

 Package : openssl
 Date    : April 5, 2013
 Affected: Business Server 1.0
 _______________________________________________________________________

 Problem Description:

 Multiple vulnerabilities has been found and corrected in openssl:
 
 OpenSSL before 0.9.8y, 1.0.0 before 1.0.0k, and 1.0.1 before 1.0.1d
 does not properly perform signature verification for OCSP responses,
 which allows remote attackers to cause a denial of service (NULL
 pointer dereference and application crash) via an invalid key
 (CVE-2013-0166).
 
 The TLS protocol 1.1 and 1.2 and the DTLS protocol 1.0 and 1.2, as used
 in OpenSSL, OpenJDK, PolarSSL, and other products, do not properly
 consider timing side-channel attacks on a MAC check requirement
 during the processing of malformed CBC padding, which allows remote
 attackers to conduct distinguishing attacks and plaintext-recovery
 attacks via statistical analysis of timing data for crafted packets,
 aka the Lucky Thirteen issue (CVE-2013-0169).
 
 The updated packages have been upgraded to the 1.0.0k version which
 is not vulnerable to these issues.
