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.
