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).
