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 Red Hat Enterprise Linux HPC Node (v. 6) - x86_64 Red Hat Enterprise Linux Server (v. 6) - i386, ppc64, s390x, x86_64 Red Hat Enterprise Linux Workstation (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 ELinksusers 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.
