Cisco IOS Software Processing of SAA Packets - Cisco Systems

high Nessus Plugin ID 55385

Synopsis

The remote device is missing a vendor-supplied security patch

Description

The Service Assurance Agent (SAA) is the new name for the Response Time Reporter (RTR) feature.
The router is vulnerable only if the RTR responder is enabled. When the router receives a malformed RTR packet, it will crash. RTR is disabled by default.
There is no workaround short of disabling the RTR responder. It is possible to mitigate the vulnerability by applying the access control list (ACL) on the router.

Solution

Apply the relevant patch referenced in Cisco Security Advisory cisco-sa-20030515-saa.
