USN-3423-1: Linux kernel vulnerability
Ubuntu Security Notice USN-3423-1
18th September, 2017
linux vulnerability
A security issue affects these releases of Ubuntu and its
derivatives:
- Ubuntu 12.04 LTS
Summary
The system could be made to crash if it received specially crafted
bluetooth traffic.
Software description
- linux
– Linux kernel
Details
It was discovered that a buffer overflow existed in the Bluetooth stack of
the Linux kernel when handling L2CAP configuration responses. A physically
proximate attacker could use this to cause a denial of service (system
crash).
Update instructions
The problem can be corrected by updating your system to the following
package version:
- Ubuntu 12.04 LTS:
-
linux-image-powerpc-smp
3.2.0.131.145
-
linux-image-3.2.0-131-omap
3.2.0-131.177
-
linux-image-3.2.0-131-powerpc-smp
3.2.0-131.177
-
linux-image-generic
3.2.0.131.145
-
linux-image-3.2.0-131-generic-pae
3.2.0-131.177

To update your system, please follow these instructions:
https://wiki.ubuntu.com/Security/Upgrades.
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.
