Synopsis :

The remote Ubuntu host is missing a security-related patch.

Description :

Vasily Kulikov discovered a flaw in the Linux Kernel's perf tool that
allows for privilege escalation. A local user could exploit this flaw
to run commands as root when using the perf tool. (CVE-2013-1060)

Michael S. Tsirkin discovered a flaw in how the Linux kernel's KVM
subsystem allocates memory slots for the guest's address space. A

sensitive information from kernel memory. (CVE-2013-1943)

A flaw was discovered in the SCTP (stream control transfer protocol)
network protocol's handling of duplicate cookies in the Linux kernel.
A remote attacker could exploit this flaw to cause a denial of service

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.
