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"

 

References
