RHSA-2013:0250 - Moderate: elinks security update
Synopsis
Moderate: elinks security update
Type/Severity
Security Advisory Moderate
Topic
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.
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.
