| ios-udp-ipc-dos-variant2 (45592) |  Medium Risk |
Description:
Cisco 10000, uBR10012 and uBR7200 devices running Cisco IOS are vulnerable to a denial of service, caused by an error when processing certain UDP packets. By sending a specially-crafted UDP packet to an interface intended for IPC communication, a remote attacker could cause the device and/or linecard to reload.

- CVE-2008-3806: Cisco IOS 12.0 through 12.4 on Cisco 10000, uBR10012 and uBR7200 series devices handles external UDP packets that are sent to 127.0.0.0/8 addresses intended for IPC communication within the device, which allows remote attackers to cause a denial of service (device or linecard reload) via crafted UDP packets, a different vulnerability than CVE-2008-3805.
