Ubuntu Security Notice USN-3404-1
August 28, 2017
linux, linux-raspi2 vulnerability
==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 17.04
Summary:
The system could be made to crash under certain conditions.
Software Description:
- linux: Linux kernel
- linux-raspi2: Linux kernel for Raspberry Pi 2
Details:
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 17.04:
linux-image-4.10.0-1016-raspi2 4.10.0-1016.19
linux-image-4.10.0-33-generic 4.10.0-33.37
linux-image-4.10.0-33-generic-lpae 4.10.0-33.37
linux-image-4.10.0-33-lowlatency 4.10.0-33.37
linux-image-generic 4.10.0.33.33
linux-image-generic-lpae 4.10.0.33.33
linux-image-lowlatency 4.10.0.33.33
linux-image-raspi2 4.10.0.1016.17
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.
