Ubuntu Security Notice USN-2583-1
April 30, 2015

linux vulnerability
==========================================================================

A security issue affects these releases of Ubuntu and its derivatives:

– Ubuntu 10.04 LTS

Summary:

The system could be made to run programs as an administrator.

Software Description:
– linux: Linux kernel

Details:

A race condition between chown() and execve() was discovered in the Linux
kernel. A local attacker could exploit this race by using chown on a
setuid-user-binary to gain administrative privileges.

Update instructions:

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

Ubuntu 10.04 LTS:
linux-image-2.6.32-74-386 2.6.32-74.142
linux-image-2.6.32-74-generic 2.6.32-74.142
linux-image-2.6.32-74-generic-pae 2.6.32-74.142
linux-image-2.6.32-74-ia64 2.6.32-74.142
linux-image-2.6.32-74-lpia 2.6.32-74.142
linux-image-2.6.32-74-powerpc 2.6.32-74.142
linux-image-2.6.32-74-powerpc-smp 2.6.32-74.142
linux-image-2.6.32-74-powerpc64-smp 2.6.32-74.142
linux-image-2.6.32-74-preempt 2.6.32-74.142
linux-image-2.6.32-74-server 2.6.32-74.142
linux-image-2.6.32-74-sparc64 2.6.32-74.142
linux-image-2.6.32-74-sparc64-smp 2.6.32-74.142
linux-image-2.6.32-74-versatile 2.6.32-74.142
linux-image-2.6.32-74-virtual 2.6.32-74.142

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.
