Debian: Security update for OpenSSL

Multiple vulnerabilities have been found in OpenSSL. OpenSSL does not properly perform signature verification for OCSP responses, which allows remote attackers to cause a denial of service via an invalid key. A timing side channel attack has been found in CBC padding allowing an attacker to recover pieces of plaintext via statistical analysis of crafted packages, known as the “Lucky Thirteen” issue.

Updated packages are available from security.debian.org.
