Debian Security Advisory DSA 144-1 security@debian.org
http://www.debian.org/security/ Martin Schulze

Package : wwwoffle
Vulnerability : improper input handling
Problem-Type : local
Debian-specific: no
CVE Id : CAN-2002-0818
A problem with wwwoffle has been discovered. The web proxy didn't
handle input data with negative Content-Length settings properly which
causes the processing child to crash. It is at this time not obvious
how this can lead to an exploitable vulnerability; however, it's better
to be safe than sorry, so here's an update.
Additionally, in the woody version empty passwords will be treated as
wrong when trying to authenticate. In the woody version we also
replaced CanonicaliseHost() with the latest routine from 2.7d, offered
by upstream. This stops bad IPv6 format IP addresses in URLs from
causing problems (memory overwriting, potential exploits).
This problem has been fixed in version 2.5c-10.4 for the old stable
distribution (potato), in version 2.7a-1.2 for the current stable
distribution (woody) and in version 2.7d-1 for the unstable
distribution (sid).
We recommend that you upgrade your wwwoffle packages.
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.
