"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).

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."
