CUPS SNMP Back End (backend/snmp.c) asn1_get_string Function Crafted SNMP Response Remote Overflow
High Nessus Plugin ID 29727
SynopsisThe remote printer service is affected by a buffer overflow vulnerability.
DescriptionAccording 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.
SolutionUpgrade to CUPS version 1.3.5 or later.
