    Debian Security Advisory DSA 285-1 security@debian.org

    Package : lprng
    Vulnerability : insecure temporary file
    Problem-Type : local
    Debian-specific: no
    CVE Id : CAN-2003-0136

    Karol Lewandowski discovered that psbanner, a printer filter that
    creates a PostScript format banner and is part of LPRng, insecurely
    creates a temporary file for debugging purpose when it is configured
    as filter. The program does not check whether this file already
    exists or is linked to another place writes its current environment
    and called arguments to the file unconditionally with the user id
    daemon.

    For the stable distribution (woody) this problem has been fixed in
    version 3.8.10-1.2.

    The old stable distribution (potato) is not affected by this problem.

    For the unstable distribution (sid) these problems have been fixed in
    version 3.8.20-4.

    We recommend that you upgrade your lprng package.
