    - -------------------------------------------------------------------------- Debian Security Advisory DSA-1841-1 [email protected] http://www.debian.org/security/ Nico Golde
    July 25th, 2009 http://www.debian.org/security/faq
    - --------------------------------------------------------------------------

    Package : git-core
    Vulnerability : denial of service
    Problem type : remote
    Debian-specific: no
    Debian bug : 532935
    CVE ID : CVE-2009-2108

    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.


    For the oldstable distribution (etch), this problem has been fixed in
    version 1.4.4.4-4+etch3.

    For the stable distribution (lenny), this problem has been fixed in
    version 1.5.6.5-3+lenny2.

    For the testing distribution (squeeze), this problem has been fixed in
    version 1:1.6.3.3-1.

    For the unstable distribution (sid), this problem has been fixed in
    version 1:1.6.3.3-1.


    We recommend that you upgrade your git-core packages.

    Upgrade instructions
    - --------------------

    wget url
    will fetch the file for you
