CVE-1999-0639

Summary

CVE-1999-0639 refers to a vulnerability in outdated implementations of the Character Generator (chargen) service. This issue arises due to insufficient input validation, allowing attackers to send specially crafted packets that could result in a buffer overflow and potential remote code execution. The chargen service, which is often run on T1 lines and X.25 networks, is particularly vulnerable if not properly secured, making this a significant threat for organizations still using these older communication protocols.
