========================================================================== Ubuntu Security Notice USN-3423-1 September 18, 2017
linux vulnerability ==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 12.04 ESM
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 versions:
Ubuntu 12.04 ESM: linux-image-3.2.0-131-generic 3.2.0-131.177 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-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-3.2.0-131-powerpc64-smp 3.2.0-131.177 linux-image-3.2.0-131-virtual 3.2.0-131.177 linux-image-generic 3.2.0.131.145 linux-image-generic-pae 3.2.0.131.145 linux-image-highbank 3.2.0.131.145 linux-image-omap 3.2.0.131.145 linux-image-powerpc-smp 3.2.0.131.145 linux-image-powerpc64-smp 3.2.0.131.145 linux-image-virtual 3.2.0.131.145
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.
