Critical Nessus Plugin ID 38099

New! Vulnerability Priority Rating (VPR)

Tenable calculates a dynamic VPR for every vulnerability. VPR combines vulnerability information with threat intelligence and machine learning algorithms to predict which vulnerabilities are most likely to be exploited in attacks. Read more about what VPR is and how it's different from CVSS.

VPR Score: 7.4


The remote Ubuntu host is missing one or more security-related patches.


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).

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.


Update the affected packages.
