    Package : arc
    Vulnerability : insecure temporary file
    Problem type : local
    Debian-specific: no
    CVE ID : CAN-2005-2945 CAN-2005-2992

    Two vulnerabilities have been discovered in the ARC archive program
    under Unix. The Common Vulnerabilities and Exposures project
    identifies the following problems:

    CAN-2005-2945

        Eric Romang discovered that the ARC archive program under Unix
        creates a temporary file with insecure permissions which may lead
        to an attacker stealing sensitive information.

    CAN-2005-2992

        Joey Schulze discovered that the temporary file was created in an
        insecure fashion as well, leaving it open to a classic symlink
        attack.

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

    For the stable distribution (sarge) these problems have been fixed in
    version 5.21l-1sarge1.

    For the unstable distribution (sid) these problems have been fixed in
    version 5.21m-1.

    We recommend that you upgrade your arc package.

    Upgrade Instructions
    - --------------------

    wget url
            will fetch the file for you
    dpkg -i file.deb
            will install the referenced file.

    If you are using the apt-get package manager, use the line for
    sources.list as given below:

    apt-get update
            will update the internal database
    apt-get upgrade
            will install corrected packages

    You may use an automated update by adding the resources from the
    footer to the proper configuration.
