Cisco IOS BGP packet denial of service and gain full control

cisco-ios-bgp-packetdos (19074)

Medium Risk

Description:

Cisco devices running vulnerable Cisco Internetworking Operating System Software (IOS) could allow a remote attacker to execute arbitrary code, or cause a denial of service. By default, the Border Gateway Protocol (BGP) is not enabled. If the device is configured with the BGP log-neighbor-changes command, a remote attacker could send a specially-crafted BGP packet, that appears to be from a trusted source, which would allow the attacker to gain full control of the affected router, or cause the device to reload.

Consequences:

Denial of Service

Remedy:

Upgrade to the latest fixed Cisco IOS version, as listed in Cisco Security Advisory 2005 January 26 1600 UTC (GMT). See References.
