USN-3145-1: Linux kernel vulnerabilities
30 November 2016
Several security issues were fixed in the kernel.
Releases
Packages
- linux - Linux kernel
Details
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 14.04
-
linux-image-3.13.0-103-generic
-
3.13.0-103.150
-
linux-image-3.13.0-103-generic-lpae
-
3.13.0-103.150
-
linux-image-3.13.0-103-lowlatency
-
3.13.0-103.150
-
linux-image-3.13.0-103-powerpc-e500
-
3.13.0-103.150
-
linux-image-3.13.0-103-powerpc-e500mc
-
3.13.0-103.150
-
linux-image-3.13.0-103-powerpc-smp
-
3.13.0-103.150
-
linux-image-3.13.0-103-powerpc64-emb
-
3.13.0-103.150
-
linux-image-3.13.0-103-powerpc64-smp
-
3.13.0-103.150
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.
