Synopsis :

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

Description :

Ben Hawkes discovered that the Linux kernel did not correctly validate

32bit system calls. On a 64bit system, a local attacker could perform
malicious multicast getsockopt calls to gain root privileges.
(CVE-2010-3081)
