From Red Hat Security Advisory 2009:1471 :
An updated elinks package that fixes two security issues is now available for Red Hat Enterprise Linux 4 and 5.
This update has been rated as having important security impact by the Red Hat Security Response Team.
ELinks is a text-based Web browser. ELinks does not display any images, but it does support frames, tables, and most other HTML tags.
An off-by-one buffer overflow flaw was discovered in the way ELinks handled its internal cache of string representations for HTML special entities. A remote attacker could use this flaw to create a specially crafted HTML file that would cause ELinks to crash or, possibly, execute arbitrary code when rendered. (CVE-2008-7224)
It was discovered that ELinks tried to load translation files using relative paths. A local attacker able to trick a victim into running ELinks in a folder containing specially crafted translation files could use this flaw to confuse the victim via incorrect translations, or cause ELinks to crash and possibly execute arbitrary code via embedded formatting sequences in translated messages. (CVE-2007-2027)
All ELinks users are advised to upgrade to this updated package, which contains backported patches to resolve these issues.
