Debian DSA-2621-1 : openssl - several vulnerabilities

medium Nessus Plugin ID 64623


The remote Debian host is missing a security-related update.


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.


Upgrade the openssl packages.

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