Debian DSA-2981-1 : polarssl - security update

medium Nessus Plugin ID 76599

Language:

Synopsis

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

Description

A flaw was discovered in PolarSSL, a lightweight crypto and SSL/TLS library, which can be exploited by a remote unauthenticated attacker to mount a denial of service against PolarSSL servers that offer GCM ciphersuites. Potentially clients are affected too if a malicious server decides to execute the denial of service attack against its clients.

Solution

Upgrade the polarssl packages.

For the stable distribution (wheezy), this problem has been fixed in version 1.2.9-1~deb7u3.
