Synopsis
=======
A stack-based buffer overflow in Git might allow a local attacker to
gain escalated privileges.

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.

Affected packages
================
    -------------------------------------------------------------------
     Package              /     Vulnerable     /            Unaffected
    -------------------------------------------------------------------
  1  dev-vcs/git                 < 1.7.2.2                 >= 1.7.2.2

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
