Description

Symptom

A vulnerability within the SNMP subsystem of Cisco IOS XE software could allow an authenticated, remote attacker to create a denial of service (DoS) condition. The vulnerability is due to an attempt to double free a region of memory when processing a series of SNMP read requests that contains certain criteria for a specific OID. An attacker with the ability to authenticate to an affected device may submit a series of valid, but specially formed SNMP requests designed to trigger the vulnerability. Successful exploitation will result in the device restarting due to an attempt to access an invalid memory region.

Conditions

Devices running software versions 3.15S, 3.16S, and 3.17S before the first fixed version of Cisco IOS-XE and configured to allow SNMP requests. The are vulnerable.
