========================================================================== Ubuntu Security Notice USN-2358-1 September 23, 2014
linux-lts-trusty vulnerabilities ==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 12.04 LTS
Summary:
Several security issues were fixed in the kernel.
Software Description: - linux-lts-trusty: Linux hardware enablement kernel from Trusty
Details:
Jack Morgenstein reported a flaw in the page handling of the KVM (Kerenl Virtual Machine) subsystem in the Linux kernel. A guest OS user could exploit this flaw to cause a denial of service (host OS memory corruption) or possibly have other unspecified impact on the host OS. (CVE-2014-3601)
Jason Gunthorpe reported a flaw with SCTP authentication in the Linux kernel. A remote attacker could exploit this flaw to cause a denial of service (NULL pointer dereference and OOPS). (CVE-2014-5077)
Chris Evans reported an flaw in the Linux kernel's handling of iso9660 (compact disk filesystem) images. An attacker who can mount a custom iso9660 image either via a CD/DVD drive or a loopback mount could cause a denial of service (system crash or reboot). (CVE-2014-5471)
Chris Evans reported an flaw in the Linux kernel's handling of iso9660 (compact disk filesystem) images. An attacker who can mount a custom iso9660 image, with a self-referential CL entry, either via a CD/DVD drive or a loopback mount could cause a denial of service (unkillable mount process). (CVE-2014-5472)
Update instructions:
The problem can be corrected by updating your system to the following package versions:
Ubuntu 12.04 LTS: linux-image-3.13.0-36-generic 3.13.0-36.63~precise1 linux-image-3.13.0-36-generic-lpae 3.13.0-36.63~precise1
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.
