RHSA-2006:0742 - Security Advisory

Topic

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.

Description

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.

Enterprise Linux 3, or the Links package shipped with Red Hat Enterprise
Linux 2.1.
