Debian DLA-1764-1 : mercurial security update

medium Nessus Plugin ID 124306

Language:

Synopsis

The remote Debian host is missing a security update.

Description

It was discovered that there was a path traversal vulnerability in the 'mercurial' distributed revision version control system.

Symbolic links and subrepositories could be used defeat Mercurial's path-checking logic and write files outside the repository root.

For Debian 8 'Jessie', this issue has been fixed in mercurial version 3.1.2-2+deb8u7.

We recommend that you upgrade your mercurial packages.

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 mercurial, and mercurial-common packages.
