How to fix?

Upgrade Debian:unstable mercurial to version 4.9-1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream mercurial package and not the mercurial package as distributed by Debian. See How to fix? for Debian:unstable relevant fixed versions and status.

A flaw was found in Mercurial before 4.9. It was possible to use symlinks and subrepositories to defeat Mercurial's path-checking logic and write files outside a repository.
