Type/Severity

Security Advisory: Critical

Topic

An updated lynx package that corrects a security flaw is now available.

This update has been rated as having critical security impact by the Red
Hat Security Response Team.

Description

Lynx is a text-based Web browser.

Ulf Harnhammar discovered a stack overflow bug in Lynx when handling
connections to NNTP (news) servers. An attacker could create a web page
redirecting to a malicious news server which could execute arbitrary code
as the user running lynx. The Common Vulnerabilities and Exposures project
assigned the name CAN-2005-3120 to this issue.

Users should update to this erratum package, which contains a backported
patch to correct this issue.
