USN-1411-1: Linux kernel vulnerability

Releases

• Ubuntu 10.04

Packages

• linux - Linux kernel

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 versions:

Ubuntu 10.04

• linux-image-2.6.32-40-generic - 2.6.32-40.87
• linux-image-2.6.32-40-sparc64-smp - 2.6.32-40.87
• linux-image-2.6.32-40-preempt - 2.6.32-40.87
• linux-image-2.6.32-40-powerpc-smp - 2.6.32-40.87
• linux-image-2.6.32-40-versatile - 2.6.32-40.87
• linux-image-2.6.32-40-powerpc64-smp - 2.6.32-40.87
• linux-image-2.6.32-40-virtual - 2.6.32-40.87
• linux-image-2.6.32-40-generic-pae - 2.6.32-40.87
• linux-image-2.6.32-40-lpia - 2.6.32-40.87
• linux-image-2.6.32-40-powerpc - 2.6.32-40.87
• linux-image-2.6.32-40-sparc64 - 2.6.32-40.87
• linux-image-2.6.32-40-server - 2.6.32-40.87
• linux-image-2.6.32-40-ia64 - 2.6.32-40.87
• linux-image-2.6.32-40-386 - 2.6.32-40.87

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.
