DESCRIPTION

* CVE-2014-0055: Insufficient error handling in vhost-net.

Insufficient error handling in vhost-net could allow a privileged user
in a guest to crash the host, leading to a denial-of-service.


* CVE-2014-2523: Remote crash via DCCP conntrack.

A flaw in the dccp protocol could allow a remote user to cause a crash
resulting in a denial-of-service.


* CVE-2014-0069: Incorrect handling of bad iovecs in CIFS.

A flaw in how CIFS handled iovecs could be used by an unprivileged local
