Description:
A vulnerability has been reported in Cisco IOS, which can be exploited by malicious people to cause a DoS (Denial of Service).
The vulnerability is caused due to an error in the handling of the SGBP protocol (Stack Group Bidding Protocol). This can be exploited to cause a vulnerable device to become unresponsive and trigger a hardware reset by sending a specially crafted UDP datagram to port 9900.
The vulnerability affects all Cisco products running the Cisco IOS software and has enabled support for the SGBP protocol.
