Cisco IOS Multiple DLSw Denial of Service Vulnerablities

Cisco IOS is prone to multiple remote denial-of-service vulnerabilities because the software fails to properly handle malformed network datagrams.

Successfully exploiting these issues allows remote attackers to trigger memory leaks or crashes in targeted devices. This will lead to denial-of-service conditions.

These issues are tracked by Cisco Bug ID CSCsk73104.

Cisco IOS Multiple DLSw Denial of Service Vulnerablities

To exploit these issues, attackers use readily available utilities for generating network packets.
