23 September 2014

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

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)

To update your system, please follow these instructions: https://wiki.ubuntu.com/Security/Upgrades.

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.
