Description

Ken Farnen discovered that Net-SNMP incorrectly handled AgentX timeouts. A remote attacker could use this issue to cause the server to crash or to hang, resulting in a denial of service. (CVE-2012-6151)

It was discovered that the Net-SNMP ICMP-MIB incorrectly validated input. A remote attacker could use this issue to cause the server to crash, resulting in a denial of service. This issue only affected Ubuntu 13.10. (CVE-2014-2284)

Viliam Pucik discovered that the Net-SNMP perl trap handler incorrectly handled NULL arguments. A remote attacker could use this issue to cause the server to crash, resulting in a denial of service. (CVE-2014-2285)

It was discovered that Net-SNMP incorrectly handled AgentX multi-object requests. A remote attacker could use this issue to cause the server to hang, resulting in a denial of service. This issue only affected Ubuntu 10.04 LTS, Ubuntu 12.04 LTS and Ubuntu 12.10. (CVE-2014-2310).

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.
