CVE-2008-0960 is an improper authentication vulnerability in SNMPv3 HMAC verification in Net-SNMP, UCD-SNMP, and numerous vendor implementations. Affected implementations trust an HMAC length supplied by the client rather than enforcing the protocol-required authentication-code length. An attacker can submit an SNMPv3 message specifying an HMAC length of one byte, causing verification of only the first byte of the authenticator and making it feasible to forge a message that passes authentication. Affected Net-SNMP releases include 5.2.x before 5.2.4.1, 5.3.x before 5.3.2.1, and 5.4.x before 5.4.1.1; Apple also shipped affected Net-SNMP in specified Mac OS X and Mac OS X Server releases.
