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:

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.
