USN-3145-2: Linux kernel (Trusty HWE) vulnerabilities
30 November 2016
Several security issues were fixed in the kernel.
Releases
Packages
- linux-lts-trusty - Linux hardware enablement kernel from Trusty for Precise
Details
USN-3145-1 fixed vulnerabilities in the Linux kernel for Ubuntu
14.04 LTS. This update provides the corresponding updates for the
Linux Hardware Enablement (HWE) kernel from Ubuntu 14.04 LTS for
Ubuntu 12.04 LTS.
Marco Grassi discovered that the driver for Areca RAID Controllers in the
Linux kernel did not properly validate control messages. A local attacker
could use this to cause a denial of service (system crash) or possibly gain
privileges. (CVE-2016-7425)
Daxing Guo discovered a stack-based buffer overflow in the Broadcom
IEEE802.11n FullMAC driver in the Linux kernel. A local attacker could use
this to cause a denial of service (system crash) or possibly gain
privileges. (CVE-2016-8658)
Update instructions
The problem can be corrected by updating your system to the following package versions:
Ubuntu 12.04
-
linux-image-generic-lpae-lts-trusty
-
3.13.0.103.94
-
linux-image-3.13.0-103-generic
-
3.13.0-103.150~precise1
-
linux-image-generic-lts-trusty
-
3.13.0.103.94
-
linux-image-3.13.0-103-generic-lpae
-
3.13.0-103.150~precise1
After a standard system update you need to reboot your computer to make
all the necessary changes.
ATTENTION: Due to an unavoidable ABI change the kernel updates have
been given a new version number, which requires you to recompile and
reinstall all third party kernel modules you might have installed.
Unless you manually uninstalled the standard kernel metapackages
(e.g. linux-generic, linux-generic-lts-RELEASE, linux-virtual,
linux-powerpc), a standard system upgrade will automatically perform
this as well.
