Synopsis
========
Multiple buffer overflow vulnerabilities have been discovered in Git.
Background
==========
Git is a distributed version control system.
Affected packages
=================
-------------------------------------------------------------------=
Package / Vulnerable / Unaffected
-------------------------------------------------------------------=
1 dev-util/git < 1.5.6.4 >= 1.5.6.=
4
Description
===========
Multiple boundary errors in the functions diff_addremove() and
diff_change() when processing overly long repository path names were
reported.
Impact
======
A remote attacker could entice a user to run commands like "git-diff"
or "git-grep" on a specially crafted repository, possibly resulting in
the remote execution of arbitrary code with the privileges of the user
running the application.
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-util/git-1.5.6.4"
