USN-3404-2: Linux kernel (HWE) vulnerability
28 August 2017
The system could be made to crash under certain conditions.
Releases
Packages
- linux-hwe - Linux hardware enablement (HWE) kernel
Details
USN-3404-1 fixed a vulnerability in the Linux kernel for Ubuntu 17.04.
This update provides the corresponding updates for the Linux Hardware
Enablement (HWE) kernel from Ubuntu 17.04 for Ubuntu 16.04 LTS.
A reference count bug was discovered in the Linux kernel ipx protocol
stack. A local attacker could exploit this flaw to cause a denial of
service or possibly other unspecified problems.
Update instructions
The problem can be corrected by updating your system to the following package versions:
Ubuntu 16.04
-
linux-image-4.10.0-33-generic
-
4.10.0-33.37~16.04.1
-
linux-image-4.10.0-33-generic-lpae
-
4.10.0-33.37~16.04.1
-
linux-image-4.10.0-33-lowlatency
-
4.10.0-33.37~16.04.1
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.
