CVE-2015-3214 (opens in a new tab)Amendment
The Ubuntu security team deemed this advisory irrelevant for Ubuntu:12.04.
NVD Description
Note: Versions mentioned in the description apply only to the upstream qemu-kvm package and not the qemu-kvm package as distributed by Ubuntu.
The pit_ioport_read in i8254.c in the Linux kernel before 2.6.33 and QEMU before 2.3.1 does not distinguish between read lengths and write lengths, which might allow guest OS users to execute arbitrary code on the host OS by triggering use of an invalid index.
