Synopsis :

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

Description :

Michael Tokarev discovered that the RTL8169 network driver did not
correctly validate buffer sizes. A remote attacker on the local
network could send specially crafted traffic that would crash the
system or potentially grant elevated privileges. (CVE-2009-1389)

Julien Tinnes and Tavis Ormandy discovered that when executing setuid
processes the kernel did not clear certain personality flags. A local
attacker could exploit this to map the NULL memory page, causing other
vulnerabilities to become exploitable. Ubuntu 6.06 was not affected.

Matt T. Yourst discovered that KVM did not correctly validate the page
table root. A local attacker could exploit this to crash the system,
leading to a denial of service. Ubuntu 6.06 was not affected.
