Summary

An unspecified vulnerability in the VLAN Trunking Protocol (VTP) implementation within Cisco IOS and CatOS can lead to a denial of service condition. When the VTP operating mode is set to a non-transparent state, an attacker could craft a malicious VTP packet directed towards a switch interface that is configured as a trunk port. This action may result in the affected device becoming unresponsive, causing it to either reload or hang, thus disrupting network operations.
