VAR-201506-0256

Vulnerability from variot - Updated: 2025-04-13 23:14

Race condition in the IPv6-to-IPv4 functionality in Cisco IOS 15.3S in the Performance Routing Engine (PRE) module on UBR devices allows remote attackers to cause a denial of service (NULL pointer free and module crash) by triggering intermittent connectivity with many IPv6 CPE devices, aka Bug ID CSCug47366. (NULL Pointer release and module crash ) There are vulnerabilities that are put into a state. Cisco IOS on uBR devices is a set of operating systems running on uBR routers from Cisco. A remote attacker can exploit the vulnerability by submitting specially crafted content to the target device (the null pointer is released and the PRE module crashes). This issue is being tracked by Cisco Bug ID CSCug47366
