"An updated elinks package that corrects a security vulnerability is
now available for Red Hat Enterprise Linux 4.

This update has been rated as having critical security impact by the
Red Hat Security Response Team.

Elinks is a text mode Web browser used from the command line that
supports rendering modern web pages.

An arbitrary file access flaw was found in the Elinks SMB protocol
handler. A malicious web page could have caused Elinks to read or
write files with the permissions of the user running Elinks.
(CVE-2006-5925)

All users of Elinks are advised to upgrade to this updated package,
which resolves this issue by removing support for the SMB protocol
from Elinks.

Note: this issue did not affect the Elinks package shipped with Red
Hat Enterprise Linux 3, or the Links package shipped with Red Hat
Enterprise Linux 2.1."
