git-daemon in git 1.4.4.5 through 1.6.3 allows remote attackers to cause a denial of service (infinite loop and CPU consumption) via a request containing extra unrecognized arguments.

A vulnerability has been found and corrected in git :

git-daemon in git 1.4.4.5 through 1.6.3 allows remote attackers to cause a denial of service (infinite loop and CPU consumption) via a request containing extra unrecognized arguments (CVE-2009-2108).

This update provides fixes for this vulnerability.

It was discovered that git-daemon which is part of git-core, a popular distributed revision control system, is vulnerable to denial of service attacks caused by a programming mistake in handling requests containing extra unrecognized arguments which results in an infinite loop. While this is no problem for the daemon itself as every request will spawn a new git-daemon instance, this still results in a very high CPU consumption and might lead to denial of service conditions.

The remote host is affected by the vulnerability described in GLSA-200907-05 (git: git-daemon Denial of Service)

    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.

This update fixes a Denial of Service vulnerability in git-daemon.

Note that Tenable Network Security has extracted the preceding description block directly from the Fedora security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

This update fixes a Denial of Service vulnerability in git-daemon. It also fixes minor issues when using git-cvsimport and the formatting of the git-daemon xinetd service description.

SecurityFocus reports :

Git is prone to a denial-of-service vulnerability because it fails to properly handle some client requests.

Attackers can exploit this issue to cause a daemon process to enter an infinite loop. Repeated exploits may consume excessive system resources, resulting in a denial of service condition.
