    Package        : qpopper
    Vulnerability  : missing privilege release
    Problem-Type   : local
    Debian-specific: no
    CVE IDs        : CAN-2005-1151 CAN-2005-1152
    This advisory does only covers updated packages for Debian 3.0 alias woody.
    Two bugs have been discovered in qpopper, an enhanced Post Office
    Protocol (POP3) server.  The Common Vulnerability and Exposures
    project identifies the following problems:
        Jens Steube discovered that while processing local files owned or
        provided by a normal user privileges weren't dropped, which could
        lead to the overwriting or creation of arbitrary files as root.
        The upstream developers noticed that qpopper could be tricked to
        creating group- or world-writable files.
    For the stable distribution (woody) these problems have been fixed in
    version 4.0.4-2.woody.5.
    For the testing distribution (sarge) these problems have been fixed in
    version 4.0.5-4sarge1.
    For the unstable distribution (sid) these problems will be fixed in
    version 4.0.5-4sarge1.
    We recommend that you upgrade your qpopper package.
