CUPS SNMP Back End (backend/snmp.c) asn1_get_string Function Crafted SNMP Response Remote Overflow

This script is Copyright (C) 2007-2016 Tenable Network Security, Inc.

Synopsis :

The remote printer service is affected by a buffer overflow

Description :

According to its banner, the version of CUPS installed on the remote
host contains a stack-based integer overflow in 'asn1_get_string' in
'backend/snmp.c'. Provided the SNMP backend is configured in CUPS
(true by default in CUPS 1.2 but not 1.3), an attacker may be able to
exploit this issue by using specially crafted SNMP responses with
negative lengths to overflow a buffer and execute arbitrary code on
the affected system.
