Debian DSA-2884-1 : libyaml - security update

medium Nessus Plugin ID 73214

Synopsis

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

Description

Ivan Fratric of the Google Security Team discovered a heap-based buffer overflow vulnerability in LibYAML, a fast YAML 1.1 parser and emitter library. A remote attacker could provide a specially crafted YAML document that, when parsed by an application using libyaml, would cause the application to crash or, potentially, execute arbitrary code with the privileges of the user running the application.

Solution

Upgrade the libyaml packages.

For the oldstable distribution (squeeze), this problem has been fixed in version 0.1.3-1+deb6u4.

For the stable distribution (wheezy), this problem has been fixed in version 0.1.4-2+deb7u4.
