## Description

AOL Desktop 9.6 contains a buffer overflow vulnerability in its Tool\rich.rct component when parsing .rtx files. By embedding an overly long string in a hyperlink tag, an attacker can trigger a stack-based buffer overflow due to the use of unsafe strcpy operations. This allows remote attackers to execute arbitrary code when a victim opens a malicious .rtx file. AOL Desktop is end-of-life and no longer supported. Users are encouraged to migrate to AOL Desktop Gold or alternative platforms.
