    Package : openvpn
    Vulnerability : several
    Problem type : remote
    Debian-specific: no
    CVE ID : CVE-2005-3393 CVE-2005-3409
    CERT advisory :
    BugTraq ID : 15239
    Debian Bug : 336751 337334

    Several vulnerabilities have been discovered in OpenVPN, a free
    virtual private network daemon. The Common Vulnerabilities and
    Exposures project identifies the following problems:

    CVE-2005-3393

        A format string vulnerability has been discovered that could allow
        arbitrary code to be executed on the client.

    CVE-2005-3409

        A NULL pointer dereferencing has been discovered that could be
        exploited to crash the service.

    The old stable distribution (woody) does not contain openvpn packages.

    For the stable distribution (sarge) these problems have been fixed in
    version 2.0-1sarge2.

    For the unstable distribution (sid) these problems have been fixed in
    version 2.0.5-1.

    We recommend that you upgrade your openvpn package.
