Cisco Security Notice
Cisco IOS XR Internet Control Message Protocol Denial of Service Vulnerability
CVE ID: CVE-2013-3464
Release Date: 2013 August 12 20:11 UTC (GMT)
Last Updated: 2013 August 12 20:11 UTC (GMT)
Cisco IOS XR Software is affected by a denial of service (DoS) vulnerability
that could allow an authenticated, local attacker to trigger a reload of the
affected device by locally generating certain Internet Control Message
Protocol (ICMP) messages.
The vulnerability is due to a combination of Silicon Packet Processor (SPP)
buffer corruption and a mutex issue when an extended ping with timeout=0 and
a large packet size is terminated with Control-C. An attacker could exploit
this vulnerability by sending large ICMP packets from an affected device.
