1. Summary:

An updated elinks package that fixes one security issue is now available
for Red Hat Enterprise Linux 5 and 6.

The Red Hat Security Response Team has rated this update as having moderate
security impact. A Common Vulnerability Scoring System (CVSS) base score,
which gives a detailed severity rating, is available from the CVE link in
the References section.

2. Relevant releases/architectures:

Red Hat Enterprise Linux (v. 5 server) - i386, ia64, ppc, s390x, x86_64
Red Hat Enterprise Linux Desktop (v. 5 client) - i386, x86_64
Red Hat Enterprise Linux Desktop (v. 6) - i386, x86_64

3. Description:

ELinks is a text-based web browser. ELinks does not display any images, but
it does support frames, tables, and most other HTML tags.

It was found that ELinks performed client credentials delegation during the
client-to-server GSS security mechanisms negotiation. A rogue server could
use this flaw to obtain the client's credentials and impersonate that
client to other servers that are using GSSAPI. (CVE-2012-4545)

This issue was discovered by Marko Myllynen of Red Hat.

All ELinks users are advised to upgrade to this updated package, which
contains a backported patch to resolve the issue.

4. Solution:

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

This update is available via the Red Hat Network. Details on how to
use the Red Hat Network to apply this update are available at
https://access.redhat.com/knowledge/articles/11258
