Debian: DSA-1663-1 Moderate: Net-SNMP Buffer Overflow and Spoofing

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.

For the stable distribution (etch), these problems has been fixed in
version 5.2.3-7etch4.

For the testing distribution (lenny) and unstable distribution (sid)
these problems have been fixed in version 5.4.1~dfsg-11.

We recommend that you upgrade your net-snmp package.
