Git: Privilege escalation

Background

Git is a free and open source distributed version control system designed to handle everything from small to very large projects with speed and efficiency.

Description

Git contains a stack-based buffer overflow in the is_git_directory function in setup.c.

Impact

A local attacker could gain escalated privileges via a specially crafted git repository.

Workaround

There is no known workaround at this time.

Resolution

All Git users should upgrade to the latest version:

 # emerge --sync
 # emerge --ask --oneshot --verbose ">=dev-vcs/git-1.7.2.2"

NOTE: This is a legacy GLSA. Updates for all affected architectures are available since September 11, 2010. It is likely that your system is already no longer affected by this issue.
