git: Multiple vulnerabilties

git: Multiple vulnerabilties Multiple vulnerabilities in gitweb allow for remote execution of arbitrary commands. git 2009-03-09 2009-03-09 251343 remote 1.6.0.6 1.6.0.6

GIT - the stupid content tracker, the revision control system used by the Linux kernel team.

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).

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.

There is no known workaround at this time.

All git users should upgrade to the latest version:


    # emerge --sync
    # emerge --ask --oneshot --verbose ">=dev-util/git-1.6.0.6"
