USN-3423-1: Linux kernel vulnerability
18 September 2017
The system could be made to crash if it received specially crafted bluetooth traffic.
Releases
Packages
- 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 versions:
Ubuntu 12.04
-
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
-
linux-image-3.2.0-131-highbank
-
3.2.0-131.177
-
linux-image-generic-pae
-
3.2.0.131.145
-
linux-image-3.2.0-131-virtual
-
3.2.0-131.177
-
linux-image-highbank
-
3.2.0.131.145
-
linux-image-virtual
-
3.2.0.131.145
-
linux-image-powerpc64-smp
-
3.2.0.131.145
-
linux-image-3.2.0-131-generic
-
3.2.0-131.177
-
linux-image-omap
-
3.2.0.131.145
-
linux-image-3.2.0-131-powerpc64-smp
-
3.2.0-131.177
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.
