CVE-2014-3672 xen: Unrestricted qemu logging
ISSUE DESCRIPTION
When the libxl toolstack launches qemu for HVM guests, it pipes the
output of stderr to a file in /var/log/xen. This output is not
rate-limited in any way. The guest can easily cause qemu to print
messages to stderr, causing this file to become arbitrarily large.
IMPACT
The disk containing the logfile can be exausted, possibly causing a
denial-of-service (DoS).
VULNERABLE SYSTEMS
All versions of Xen are affected.
Only x86 systems are affected; ARM systems are not affected.
Only systems running HVM guests are affected; systems running only PV
guests are not affected.
Both qemu-upstream and qemu-traditional are affected.
MITIGATION
Running only PV guests will avoid this vulnerability.
