Ubuntu Security Notice USN-2415-1
November 25, 2014
linux vulnerability
==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
– Ubuntu 10.04 LTS
Summary:
The system could be made to deny write access to files.
Software Description:
– linux: Linux kernel
Details:
Andy Lutomirski discovered that the Linux kernel was not checking the
CAP_SYS_ADMIN when remounting filesystems to read-only. A local user could
exploit this flaw to cause a denial of service (loss of writability).
Update instructions:
The problem can be corrected by updating your system to the following
package versions:
Ubuntu 10.04 LTS:
linux-image-2.6.32-68-386 2.6.32-68.135
linux-image-2.6.32-68-generic 2.6.32-68.135
linux-image-2.6.32-68-generic-pae 2.6.32-68.135
linux-image-2.6.32-68-ia64 2.6.32-68.135
linux-image-2.6.32-68-lpia 2.6.32-68.135
linux-image-2.6.32-68-powerpc 2.6.32-68.135
linux-image-2.6.32-68-powerpc-smp 2.6.32-68.135
linux-image-2.6.32-68-powerpc64-smp 2.6.32-68.135
linux-image-2.6.32-68-preempt 2.6.32-68.135
linux-image-2.6.32-68-server 2.6.32-68.135
linux-image-2.6.32-68-sparc64 2.6.32-68.135
linux-image-2.6.32-68-sparc64-smp 2.6.32-68.135
linux-image-2.6.32-68-versatile 2.6.32-68.135
linux-image-2.6.32-68-virtual 2.6.32-68.135
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.
