Description

The Debian stable point release 5.0.6 included updated packages of the Git revision control system in order to fix a security issue. Unfortunately, the update introduced a regression which could make it impossible to clone or create Git repositories. This upgrade fixes this regression, which is tracked as Debian bug #595728.

The original security issue allowed an attacker to execute arbitrary code if he could trick a local user to execute a git command in a crafted working directory (CVE-2010-2542 ).
