Ubuntu Security Notice USN-1408-1
27th March, 2012
linux-fsl-imx51 vulnerability
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 10.04 LTS
Summary
The system could be made to crash under certain conditions.
Software description
- linux-fsl-imx51 - Linux kernel for IMX51
Details
Louis Rilling discovered a flaw in Linux kernel's clone command when
CLONE_IO is specified. An unprivileged local user could exploit this to
cause a denial of service.
Update instructions
The problem can be corrected by updating your system to the following package version:
- Ubuntu 10.04 LTS:
- linux-image-2.6.31-612-imx51 2.6.31-612.34
To update your system, please follow these instructions: https://wiki.ubuntu.com/Security/Upgrades.
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.
