fetchmail, fetchmail-ssl buffer overflows

Debian Security Advisory DSA 171-1                                        Martin Schulze

[ Resent since this advisory did not appear in the list archive. ]

Package        : fetchmail, fetchmail-ssl
Vulnerability  : buffer overflows
Problem-Type   : remote
Debian-specific: no

Stefan Esser discovered several buffer overflows and a broken boundary
check within fetchmail.  If fetchmail is running in multidrop mode
these flaws can be used by remote attackers to crash it or to execute
arbitrary code under the user id of the user running fetchmail.
Depending on the configuration this even allows a remote root

These problems have been fixed in version 5.9.11-6.1 for both
fetchmail and fetchmail-ssl for the current stable distribution
(woody), in version 5.3.3-4.2 for fetchmail for the old stable
distribution (potato) and in version 6.1.0-1 for both fetchmail and
fetchmail-ssl for the unstable distribution (sid).  There are no
fetchmail-ssl packages for the old stable distribution (potato) and
thus no updates.

We recommend that you upgrade your fetchmail packages immediately.

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.
