Debian DSA-3115-1 : pyyaml - security update

medium Nessus Plugin ID 80286

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 Python-YAML, a YAML parser and emitter for Python. An attacker able to load specially crafted YAML input into an application using python-yaml could cause the application to crash.

Solution

Upgrade the pyyaml packages.

For the stable distribution (wheezy), this problem has been fixed in version 3.10-4+deb7u1.

For the upcoming stable distribution (jessie), this problem has been fixed in version 3.11-2.
