3) An error within the event management code can be exploited to
execute arbitrary JavaScript with chrome privileges.

4) A use-after-free error within the handling of the ".appendChild()"
method when importing certain objects can be exploited to can be
exploited to dereference an invalid pointer.

5) An error when dropping a tab element in content areas can be
exploited to execute arbitrary code with chrome privileges.

6) The "ThinkPadSensor::Startup()" function loads libraries in an
insecure manner and can be exploited to load arbitrary libraries by
tricking a user into opening a specially crafted file located on a
remote WebDAV or SMB share.

7) An error when handling the "RegExp.input()" function can be
exploited to read data from other domains.

The vulnerabilities are reported in the following products:
