Synopsis

The remote Gentoo host is missing one or more security-related patches.

Description

The remote host is affected by the vulnerability described in GLSA-200903-15 (git: Multiple vulnerabilities)

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.

Solution

All git users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose '>=dev-util/git-1.6.0.6'
