CVE-2014-3672

Published: 25 May 2016

The qemu implementation in libvirt before 1.3.0 and Xen allows local guest OS users to cause a denial of service (host disk consumption) by writing to stdout or stderr.

Notes

AuthorNote
mdeslaur
as of 2017-08-01, no equivalent fix in qemu tree. Unlikely to
be fixed in qemu. As such, marking as ignored in qemu.

the libvirt fix changes behaviour, we are not going to backport
the new log location to trusty.
