Debian DSA-3102-1 : libyaml - security update

medium Nessus Plugin ID 79889

Language:

Synopsis

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

Description

Jonathan Gray and Stanislaw Pitucha found an assertion failure in the way wrapped strings are parsed in LibYAML, a fast YAML 1.1 parser and emitter library. An attacker able to load specially crafted YAML input into an application using libyaml could cause the application to crash.

Solution

Upgrade the libyaml packages.

For the stable distribution (wheezy), this problem has been fixed in version 0.1.4-2+deb7u5.

For the upcoming stable distribution (jessie), this problem has been fixed in version 0.1.6-3.
