- -------------------------------------------------------------------------- Debian Security Advisory DSA 144-1 security@debian.org http://www.debian.org/security/ Martin Schulze August 6th, 2002 - -------------------------------------------------------------------------- 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.
