Cisco IOS 15.0 through 15.3 and IOS XE 3.2 through 3.8, when a VRF interface exists, allows remote attackers to cause a denial of service (interface queue wedge) via crafted UDP RSVP packets, aka Bug ID CSCuf17023. Cisco IOS is the interconnected network operating system used on most Cisco system routers and network switches. The vulnerability is caused by incorrectly parsing UDP RSVP packets. The attacker can send UDP RSVP packets to the affected device to exploit the vulnerability. Wedge), which can cause link loss, interrupt communication and other denial of service conditions.
