Debian Security Advisory DSA 144-1                     security@debian.org

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.
