Debian DSA-1663-1 : net-snmp - several vulnerabilities
Critical Nessus Plugin ID 34720
The remote Debian host is missing a security-related update.
Several vulnerabilities have been discovered in NET SNMP, a suite of Simple Network Management Protocol applications. The Common Vulnerabilities and Exposures project identifies the following problems : - CVE-2008-0960 Wes Hardaker reported that the SNMPv3 HMAC verification relies on the client to specify the HMAC length, which allows spoofing of authenticated SNMPv3 packets. - CVE-2008-2292 John Kortink reported a buffer overflow in the __snprint_value function in snmp_get causing a denial of service and potentially allowing the execution of arbitrary code via a large OCTETSTRING in an attribute value pair (AVP). - CVE-2008-4309 It was reported that an integer overflow in the netsnmp_create_subtree_cache function in agent/snmp_agent.c allows remote attackers to cause a denial of service attack via a crafted SNMP GETBULK request.
Upgrade the net-snmp package. For the stable distribution (etch), these problems has been fixed in version 5.2.3-7etch4.
