Ulf Härnhammar 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.
