TITLE

Cisco IOS XR Software UDP Packet Denial of Service Vulnerability

Trust: 0.9

sources: CNVD: CNVD-2013-13516 // BID: 62770

DESCRIPTION

The UDP process in Cisco IOS XR 4.3.1 does not free packet memory upon detecting full packet queues, which allows remote attackers to cause a denial of service (memory consumption) via UDP packets to listening ports, aka Bug ID CSCue69413. ( Memory consumption ) There is a vulnerability that can be exploited. Cisco IOS XR is a member of the Cisco IOS Software family that uses a microkernel-based operating system architecture. The device cannot allocate memory for packets, causing a denial of service attack. An attacker can exploit this issue to exhaust all available memory and cause a denial-of-service condition. This issue is being tracked by Cisco Bug ID CSCue69413
