Ubuntu 11.10 USN-1554-1 Critical Denial of Service in Linux Kernel

ubuntu
Calendar Grey September 5, 2012
Scroller Ubuntu
A flaw in the Linux kernel could cause system failures under specific conditions. Ubuntu users are advised to update their systems to avoid potential denial-of-service issues
The system could be made to crash under certain conditions.

Summary

The system could be made to crash under certain conditions.

Software Description:

- linux: Linux kernel

Details:

A flaw was found in the Linux kernel's Reliable Datagram Sockets (RDS)

protocol implementation. A local, unprivileged user could use this flaw to

cause a denial of service.

Update Instructions

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

Ubuntu 11.10:
  linux-image-3.0.0-25-generic    3.0.0-25.41
  linux-image-3.0.0-25-generic-pae  3.0.0-25.41
  linux-image-3.0.0-25-omap       3.0.0-25.41
  linux-image-3.0.0-25-powerpc    3.0.0-25.41
  linux-image-3.0.0-25-powerpc-smp  3.0.0-25.41
  linux-image-3.0.0-25-powerpc64-smp  3.0.0-25.41
  linux-image-3.0.0-25-server     3.0.0-25.41
  linux-image-3.0.0-25-virtual    3.0.0-25.41

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. If
you use linux-restricted-modules, you have to update that package as
well to get modules which work with the new kernel version. Unless you
manually uninstalled the standard kernel metapackages (e.g. linux-generic,
linux-server, linux-powerpc), a standard system upgrade will automatically
perform this as well.
