Vivian Zhang and Christoph Anton Mitterer discovered that setting an
empty VNC password does not work as documented in Libvirt, a
virtualisation abstraction library. When the password on a VNC server is
set to the empty string, authentication on the VNC server will be
disabled, allowing any user to connect, despite the documentation
declaring that setting an empty password for the VNC server prevents all
client connections. With this update the behaviour is enforced by
setting the password expiration to now.

The TERASOLUNA Framework Development Team discovered a denial of service
vulnerability in Apache Commons FileUpload, a package to make it
easy to add robust, high-performance, file upload capability to servlets
and web applications. A remote attacker can take advantage of this flaw
by sending file upload requests that cause the HTTP server using the
Apache Commons Fileupload library to become unresponsive, preventing the
server from servicing other requests.

Multiple vulnerabilities were discovered in the dissectors/parsers for
PKTC, IAX2, GSM CBCH and NCP, SPOOLS, IEEE 802.11, UMTS FP, USB,
Toshiba, CoSine, NetScreen, WBXML which could result in denial of service
or potentially the execution of arbitrary code.
