Synopsis

========

 

Multiple vulnerabilities in gitweb allow for remote execution of

arbitrary commands.

 

Background

==========

 

GIT - the stupid content tracker, the revision control system used by

the Linux kernel team.

 

Affected packages

=================

 

-------------------------------------------------------------------

Package / Vulnerable / Unaffected

-------------------------------------------------------------------

1 dev-util/git < 1.6.0.6 >= 1.6.0.6

 

Description

===========

 

Multiple vulnerabilities have been reported in gitweb that is part of

the git package:

 

* Shell metacharacters related to git_search are not properly

sanitized (CVE-2008-5516).

 

* Shell metacharacters related to git_snapshot and git_object are not

properly sanitized (CVE-2008-5517).

 

* The diff.external configuration variable as set in a repository can

be executed by gitweb (CVE-2008-5916).

 

Impact

======

 

A remote unauthenticated attacker can execute arbitrary commands via

shell metacharacters in a query, remote attackers with write access to

a git repository configuration can execute arbitrary commands with the

privileges of the user running gitweb by modifying the diff.external

configuration variable in the repository and sending a crafted query to

gitweb.

 

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-1.6.0.6"
