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"
