Description

Cisco products contain multiple vulnerabilities in handling of SNMP requests and traps. A general report for multiple vendors was initially published on February 12 (SNMP-GENERIC-0001), however more information is now available and a separate id has been allocated for the Cisco IOS vulnerabilities.

It is reportedly possible for a remote attacker to create a denial of service by transmitting malformed SNMP packet to a device running a vulnerable version of IOS. The affected device may reset, or (under rare circumstances) require a manual reset to regain functionality.

The nature of these denial of service conditions is not known. They may be due to exploitable buffer overflow conditions.
