Debian DSA-251-1 : w3m - missing HTML quoting

medium Nessus Plugin ID 15088

Synopsis

The remote Debian host is missing a security-related update.

Description

Hironori Sakamoto, one of the w3m developers, found two security vulnerabilities in w3m and associated programs. The w3m browser does not properly escape HTML tags in frame contents and img alt attributes. A malicious HTML frame or img alt attribute may deceive a user to send their local cookies which are used for configuration. The information is not leaked automatically, though.

Solution

Upgrade the w3m and w3m-ssl packages.

For the stable distribution (woody) these problems have been fixed in version 0.3-2.4.

The old stable distribution (potato) is not affected by these problems.
