Debian DLA-1414-2 : mercurial regression update

Critical Nessus Plugin ID 110927

Synopsis

The remote Debian host is missing a security update.

Description

The fix for arbitrary code execution documented in CVE-2017-17458 was incomplete in the previous upload. A more exhaustive change was implemented upstream and completely disables non-Mercurial subrepositories unless users changed the subrepos.allowed setting.

For Debian 8 'Jessie', this problem has been fixed in version 3.1.2-2+deb8u6.

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.
