Debian Security Advisory DSA 251-1                     security@debian.org

--------------------------------------------------------------------------

Package        : w3m, w3m-ssl
Vulnerability  : missing HTML quoting
Problem-Type   : remote
Debian-specific: no
CVE Id         : CAN-2002-1335 CAN-2002-1348

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.


Upgrade Instructions
--------------------

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.
