Debian 3.0: DSA 251-1 Critical: W3m HTML Quoting Remote Threat

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 his local cookies which are used for configuration. The
information is not leaked automatically, though.

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.

For the unstable distribution (sid) these problems have been fixed in
version 0.3.2.2-1 and later.

We recommend that you upgrade your w3m and w3m-ssl packages.
