    Exclamation Vulnerability:Caldera-Remote attack on rsync

    Sebastian Krahmer of SuSE discovered a vulnerability in rsync that
    allows an attacker to modify memory of the rsync server process. There
    is no know exploit yet, but this vulernability could be used against
    servers providing downloads via anonymous rsync. Note that the problem
    can also be exploited by a rogue server, attacking a client who uses
    rsync.

    Thanks a TON for this post. I need to update my OpenLinux 2.3 to the latest stuff anyway, and I've been meaning to, and you've reminded me. Thanks again.
