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