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

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
