Gentoo Linux Security Advisory

Title: git: git-daemon Denial of Service (GLSA 200907-05)
Severity: normal
Exploitable: remote
Date: July 12, 2009
Bug(s): #273905
ID: 200907-05

Synopsis

An error in git-daemon might lead to a Denial of Service via resource consumption.

Background

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

Affected Packages

Package: dev-util/git
Vulnerable: < 1.6.3.3
Unaffected: >= 1.6.3.3
Architectures: All supported architectures


Description

Shawn O. Pearce reported that git-daemon runs into an infinite loop when handling requests that contain unrecognized arguments.

Impact

A remote unauthenticated attacker could send a specially crafted request to git-daemon, possibly leading to a Denial of Service (CPU consumption).

Workaround

There is no known workaround at this time.

Resolution

All git users should upgrade to the latest version:
Code:
# emerge --sync
# emerge --ask --oneshot --verbose ">=dev-util/git-1.6.3.3"
