| Description: | Summary:
The remote host is missing an update for the 'linux' package(s) announced via the USN-974-2 advisory.
Vulnerability Insight:
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.
Original advisory details:
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)
Affected Software/OS:
'linux' package(s) on Ubuntu 8.04.
Solution:
Please install the updated package(s).
CVSS Score:
