CVEs ( CVE-2002-1335


New w3m packages are available that fix two cross-site scripting issues.

w3m is a pager with Web browsing capabilities. Two cross-site scripting
(XSS) issues have been found in w3m.

An XSS vulnerability in w3m 0.3.2 allows remote attackers to insert
arbitrary HTML and web script into frames. Frames are disabled by default
in the version of w3m shipped with Red Hat Linux. Therefore, this problem
will not appear as long as users do not use w3m with the -F option, or
enable frame support in either the /etc/w3m/w3mconfig or ~/.w3m/config
configuration files. The Common Vulnerabilities and Exposures project
( has assigned the name CAN-2002-1335 to this issue.

An XSS vulnerability in versions of w3m before allows attackers to
insert arbitrary HTML and web script into image attributes. The Common
Vulnerabilities and Exposures project ( has assigned the name
CAN-2002-1348 to this issue

Users of w3m under Red Hat Linux versions 7.0J, 7.2, 7.3, and 8.0 are
advised to upgrade to the updated packages containing w3m 0.3.1 with
a patch to correct these issues.


Before applying this update, make sure all previously released errata
relevant to your system have been applied.

To update all RPMs for your particular architecture, run:

rpm -Fvh [filenames]

where [filenames] is a list of the RPMs you wish to upgrade. Only those
RPMs which are currently installed will be updated. Those RPMs which are
not installed but included in the list will not be updated. Note that you
can also use wildcards (*.rpm) if your current directory *only* contains
the desired RPMs.

Please note that this update is also available via Red Hat Network. Many
people find this an easier way to apply updates. To use Red Hat Network,
launch the Red Hat Update Agent with the following command:


This will start an interactive process that will result in the appropriate
RPMs being upgraded on your system.
