Debian DLA-2600-1 : pygments security update

high Nessus Plugin ID 147926

Language:

Synopsis

The remote Debian host is missing a security update.

Description

It was discovered that there was a series of denial of service vulnerabilities in Pygments, a popular syntax highlighting library for Python.

A number of regular expressions had exponential or cubic worst-case complexity which could cause a remote denial of service (DoS) when provided with malicious input.

For Debian 9 'Stretch', this problem has been fixed in version 2.2.0+dfsg-1+deb9u2.

We recommend that you upgrade your pygments packages.

For the detailed security status of pygments please refer to its security tracker page at:
https://security-tracker.debian.org/tracker/pygments

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.
