    Debian Security Advisory DSA 725-2 security@debian.org

    July 4th, 2005 http://www.debian.org/security/faq
    - --------------------------------------------------------------------------

    Package : ppxp
    Vulnerability : missing privilege release
    Problem-Type : local
    Debian-specific: no
    CVE ID : CAN-2005-0392

    Jens Steube discovered that ppxp, yet another PPP program, does not
    release root privileges when opening potentially user supplied log
    files. This can be tricked into opening a root shell.

    For the old stable distribution (woody) this problem has been
    fixed in version 0.2001080415-6woody1 (DSA 725-1).

    For the stable distribution (sarge) this problem has been fixed in
    version 0.2001080415-10sarge2.

    For the unstable distribution (sid) this problem has been fixed in
    version 0.2001080415-11.

    We recommend that you upgrade your ppxp package.

    Upgrade Instructions
