CVE-2000-0453 describes a denial-of-service vulnerability affecting XFree86 versions 3.3.x and 4.0. An unauthenticated attacker can exploit this by sending a specially crafted TCP packet with a negative counter value to port 6000, causing the X server to crash. This vulnerability has a CVSS score of 5.0 (Medium) due to its network-based attack vector and low attack complexity, leading to a partial availability impact. While there is no evidence of active exploitation, a public exploit (EDB-19950) exists, though it has received minimal community discussion or media coverage.
