McCreight, Joe Drew, Wayne Mery, Alon Zakai, Christian Holler, Gary
Kwong, Luke Wagner, Terrence Cole, Timothy Nikkel, Bill McCloskey, and
Nicolas Pierron discovered multiple memory safety issues affecting

Boris Zbarsky discovered that Firefox did not properly handle some
wrapped WebIDL objects. If the user were tricked into opening a
specially crafted page, an attacker could possibly exploit this to
cause a denial of service via application crash, or potentially
execute code with the privileges of the user invoking Firefox.
(CVE-2013-0765)

Bobby Holley discovered vulnerabilities in Chrome Object Wrappers
(COW) and System Only Wrappers (SOW). If a user were tricked into
opening a specially crafted page, a remote attacker could exploit this

Firefox. (CVE-2013-0773)

Frederik Braun that Firefox made the location of the active browser
