A vulnerability has been reported in CUPS, which can be exploited by malicious people to cause a DoS (Denial of Service) or potentially compromise a vulnerable system. The vulnerability is caused due to a signedness error within the “asn1_get_string()” function in backend/snmp.c. This can be exploited to cause a stack-based buffer overflow via specially crafted SNMP responses containing ASN1 encoded strings with negative length values. Successful exploitation on 1.3.x versions requires that the snmp backend is configured in snmp.conf.
