Multiple vulnerabilities have been found in OpenSSL. The Common Vulnerabilities and Exposures project identifies the following issues :
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.
