Descriptions

The cat6000-dot1x component in Cisco IOS 12.2 before 12.2(33)SXI7 does not properly handle (1) a loop between a dot1x enabled port and an open-authentication dot1x enabled port and (2) a loop between a dot1x enabled port and a non-dot1x port, which allows remote attackers to cause a denial of service (traffic storm) via unspecified vectors that trigger many Spanning Tree Protocol (STP) Bridge Protocol Data Unit (BPDU) frames, aka Bug ID CSCtq36327.

El componente cat6000-dot1x en Cisco IOS v12.2 anterior a v12.2(33)SXI7 no controla correctamente (1) un bucle entre un puerto dot1x activado y una puerto habilitado para autenticación abierta dot1x y (2) un bucle entre un puerto dot1x habilitado y un puerto no dot1x, lo que permite a atacantes remotoso provocar una denegación de servicio (tormenta de tráfico) a través de vectores no especificados que disparan muchas tramas Spanning Tree Protocol (STP) Bridge Protocol Data Unit (BPDU) también conocido como Bug ID CSCtq36327.
