Vigil@nce - Cisco IOS XR: memory leak via SNMP
June 2013 by Vigil@nce
This bulletin was written by Vigil@nce : http://vigilance.fr/offer
SYNTHESIS OF THE VULNERABILITY
An attacker can send SNMP packets to Cisco IOS XR, to create a
memory leak, in order to trigger a denial of service.
Impacted products: IOS XR
Severity: 2/4
Creation date: 23/05/2013
DESCRIPTION OF THE VULNERABILITY
The SNMP service uses the port 162/udp to manage Trap and
InformRequest messages.
However, if one of these messages is malformed, Cisco IOS XR does
not free an allocated memory area.
An attacker can therefore send SNMP packets to Cisco IOS XR, to
create a memory leak, in order to trigger a denial of service.
