Details

Wes Hardaker discovered that the SNMP service did not correctly validate
HMAC authentication requests. An unauthenticated remote attacker
could send specially crafted SNMPv3 traffic with a valid username
and gain access to the user’s views without a valid authentication
passphrase. (CVE-2008-0960)

John Kortink discovered that the Net-SNMP Perl module did not correctly
check the size of returned values. If a user or automated system were
tricked into querying a malicious SNMP server, the application using
the Perl module could be made to crash, leading to a denial of service.
This did not affect Ubuntu 8.10. (CVE-2008-2292)

It was discovered that the SNMP service did not correctly handle large
GETBULK requests. If an unauthenticated remote attacker sent a specially
crafted request, the SNMP service could be made to crash, leading to a
denial of service. (CVE-2008-4309)
