Ubuntu Security Notice USN-2511-1

linux vulnerabilities
============================================================================

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

- Ubuntu 10.04 LTS

Summary:

Several security issues were fixed in the kernel.

Software Description:
- linux: Linux kernel

Details:

A race condition was discovered in the Linux kernel's key ring. A local
user could cause a denial of service (memory corruption or panic) or
possibly have unspecified impact via the keyctl commands. (CVE-2014-9529)

A memory leak was discovered in the ISO 9660 CDROM file system when parsing
rock ridge ER records. A local user could exploit this flaw to obtain
sensitive information from kernel memory via a crafted iso9660 image.
(CVE-2014-9584)

Update instructions:

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

Ubuntu 10.04 LTS:
linux-image-2.6.32-73-386 2.6.32-73.140
linux-image-2.6.32-73-generic 2.6.32-73.140
linux-image-2.6.32-73-generic-pae 2.6.32-73.140
linux-image-2.6.32-73-ia64 2.6.32-73.140
linux-image-2.6.32-73-lpia 2.6.32-73.140
linux-image-2.6.32-73-powerpc 2.6.32-73.140
linux-image-2.6.32-73-powerpc-smp 2.6.32-73.140
linux-image-2.6.32-73-powerpc64-smp 2.6.32-73.140
linux-image-2.6.32-73-preempt 2.6.32-73.140
linux-image-2.6.32-73-server 2.6.32-73.140
linux-image-2.6.32-73-sparc64 2.6.32-73.140
linux-image-2.6.32-73-sparc64-smp 2.6.32-73.140
linux-image-2.6.32-73-versatile 2.6.32-73.140
linux-image-2.6.32-73-virtual 2.6.32-73.140

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.
