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)

Update instructions

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

Ubuntu 10.04

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.
