CVE-2013-0166

OpenSSL does not properly perform signature verification for OCSP responses, which allows remote attackers to cause a denial of service via an invalid key.

CVE-2013-0169

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.

For the stable distribution (squeeze), these problems have been fixed in version 0.9.8o-4squeeze14.

For the testing distribution (wheezy), these problems will be fixed soon.

For the unstable distribution (sid), these problems have been fixed in version 1.0.1e-1.

We recommend that you upgrade your openssl packages.");
