net-snmp - several vulnerabilities

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.

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.
