Ubuntu Security Notice (C) 2010-2013 Canonical, Inc. / NASL script (C) 2010-2013 Tenable Network Security, Inc.


Synopsis :

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

Description :

USN-974-1 fixed vulnerabilities in the Linux kernel. The fixes for
CVE-2010-2240 caused failures for Xen hosts. This update fixes the
problem.

We apologize for the inconvenience.

Gael Delalleu, Rafal Wojtczuk, and Brad Spengler discovered that the
memory manager did not properly handle when applications grow stacks
into adjacent memory regions. A local attacker could exploit this to
gain control of certain applications, potentially leading to privilege
escalation, as demonstrated in attacks against the X server.
(CVE-2010-2240)

Kees Cook discovered that under certain situations the ioctl
subsystem for DRM did not properly sanitize its arguments. A
local attacker could exploit this to read previously freed
kernel memory, leading to a loss of privacy. (CVE-2010-2803)

Ben Hawkes discovered an integer overflow in the Controller
Area Network (CAN) subsystem when setting up frame content
and filtering certain messages. An attacker could send
specially crafted CAN traffic to crash the system or gain
root privileges. (CVE-2010-2959).

Solution :

Update the affected packages.

Risk factor :

High / CVSS Base Score : 7.2
