Descriptions

Unspecified vulnerability in Cisco IOS 12.2 and 12.4, when the L2TP mgmt daemon process is enabled, allows remote attackers to cause a denial of service (device reload) via a crafted L2TP packet.

Vulnerabilidad no especificada en Cisco IOS v12.2 y v12.4. Cuando está habilitado el proceso de demonio del L2TP (Layer 2 Tunneling Protocol) mgmt permite a atacantes remotos causar denegación de servicio (reinicio de dispositivo) a través un paquete L2TP manipulado.

A vulnerability exists in the Cisco IOS software implementation of Layer 2 Tunneling Protocol (L2TP), which affects limited Cisco IOS software releases. Several features enable the L2TP mgmt daemon process within Cisco IOS software, including but not limited to Layer 2 virtual private networks (L2VPN), Layer 2 Tunnel Protocol Version 3 (L2TPv3), Stack Group Bidding Protocol (SGBP) and Cisco Virtual Private Dial-Up Networks (VPDN). Once this process is enabled the device is vulnerable. This vulnerability will result in a reload of the device when processing a specially crafted L2TP packet. Cisco has released free software updates that address this vulnerability.
