Ubuntu Security Notice USN-1554-1
September 05, 2012
linux vulnerability
==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 11.10
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.
