Debian Security Advisory DSA 728-1                     security@debian.org

- --------------------------------------------------------------------------

Package        : qpopper
Vulnerability  : missing privilege release
Problem-Type   : local
Debian-specific: no
CVE IDs        : CAN-2005-1151 CAN-2005-1152

Two bugs have been discovered in qpopper, an enhanced Post Office
Protocol (POP3) server.  The Common Vulnerability and Exposures
project identifies the following problems:

CAN-2005-1151

    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.

CAN-2005-1152

    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.


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.
