USN-3290-1: Linux kernel vulnerability
17 May 2017
The system could be made to crash under certain conditions.
Releases
Packages
- linux - Linux kernel
Details
Marco Grassi discovered that the TCP implementation in the Linux kernel
mishandles socket buffer (skb) truncation. A local 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 14.04
-
linux-image-3.13.0-119-generic
-
3.13.0-119.166
-
linux-image-3.13.0-119-generic-lpae
-
3.13.0-119.166
-
linux-image-3.13.0-119-lowlatency
-
3.13.0-119.166
-
linux-image-3.13.0-119-powerpc-e500
-
3.13.0-119.166
-
linux-image-3.13.0-119-powerpc-e500mc
-
3.13.0-119.166
-
linux-image-3.13.0-119-powerpc-smp
-
3.13.0-119.166
-
linux-image-3.13.0-119-powerpc64-smp
-
3.13.0-119.166
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.
