VAR-200908-0252
Vulnerability from variot - Updated: 2025-04-10 22:56Cisco IOS XR 3.8.1 and earlier allows remote attackers to cause a denial of service (process crash) via a long BGP UPDATE message, as demonstrated by a message with many AS numbers in the AS Path Attribute. An attacker can exploit this issue to cause the BGP process to crash, creating a denial-of-service condition. This issue is being tracked by Cisco Bug ID CSCtb05382. Cisco IOS is an operating system developed by Cisco in the United States for its network equipment. The number of AS numbers must exceed the full or maximum length of the update message to trigger this vulnerability
