New! Plugin Severity Now Using CVSS v3

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 local user could exploit this flaw to gain system privileges or obtain 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 (system crash) on another remote user querying the SCTP connection.
(CVE-2013-2206)

Hannes Frederic Sowa discovered a flaw in setsockopt UDP_CORK option in the Linux kernel's IPv6 stack. A local user could exploit this flaw to cause a denial of service (system crash). (CVE-2013-4162).

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.
