USN-3313-1: Linux kernel vulnerability

06 June 2017

The system could be made to run programs as an administrator.

Releases

Packages

Details

It was discovered that a buffer overflow existed in the trace subsystem in
the Linux kernel. A privileged local attacker could use this to execute
arbitrary code.

Update instructions

The problem can be corrected by updating your system to the following package versions:

Ubuntu 16.10

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.
