http://security.gentoo.org/

Severity:	normal
Title:	Git: User-assisted execution of arbitrary code
Date:	09/25/2008
Bugs:	#234075
ID:	200809-16

Synopsis

Multiple buffer overflow vulnerabilities have been discovered in Git.

Background

Git is a distributed version control system.

Affected packages

Package	Vulnerable	Unaffected	Architecture(s)
dev-util/git	< 1.5.6.4	>= 1.5.6.4	All supported architectures

Description

Multiple boundary errors in the functions diff_addremove() and diff_change() when processing overly long repository path names were reported.

Impact

A remote attacker could entice a user to run commands like "git-diff" or "git-grep" on a specially crafted repository, possibly resulting in the remote execution of arbitrary code with the privileges of the user running the application.

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-1.5.6.4"
