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"
