Description:
David Barroso Berrueta and Alfredo Andres Omella have reported a vulnerability in Cisco IOS, which can be exploited by malicious people to cause a DoS (Denial of Service).
The vulnerability is caused due to an unspecified error when handling certain malformed VLAN Trunking Protocol (VTP) packets. This can be exploited to cause a device to reload by sending a specially crafted VTP packet.
Successful exploitation requires knowledge of the VTP domain name and the port that is configured for trunking.
The vulnerability is reported in the following devices:
* Cisco 2900XL Series Switches
* Cisco 2950 Series Switches
* Cisco 2955 Series Switches
* Cisco 3500XL Series Switches
* Cisco 3550 Series Switches
* Cisco 3570 Series Switches
