Debian DLA-127-1 : pyyaml security update

medium Nessus Plugin ID 82110

Language:

Synopsis

The remote Debian host is missing a security 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.

NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Upgrade the affected packages.
