Use-after-free while manipulating DOM events and removing audio elements due to errors in the handling of node adoption (CVE-2016-9899). Event handlers on marquee elements were executed despite a strict Content Security Policy (CSP) that disallowed inline JavaScript (CVE-2016-9895). Memory corruption resulting in a potentially exploitable crash during WebGL functions using a vector constructor with a varying array within libGLES (CVE-2016-9897). Use-after-free resulting in potentially exploitable crash when manipulating DOM subtrees in the Editor (CVE-2016-9898). External resources that should be blocked when loaded by SVG images can bypass security restrictions through the use of data: URLs. This could allow for cross-domain data leakage (CVE-2016-9900). An attacker could use a JavaScript Map/Set timing attack to determine whether an atom is used by another compartment/zone in specific contexts. This could be used to leak information, such as usernames embedded in JavaScript code, across websites (CVE-2016-9904). A potentially exploitable crash in EnumerateSubDocuments while adding or removing sub-documents (CVE-2016-9905). Mozilla developers and community members Jan de Mooij, Iris Hsiao, Christian Holler, Carsten Book, Timothy Nikkel, Christoph Diehl, Olli Pettay, Raymond Forbes, and Boris Zbarsky reported memory safety bugs present in in Thunderbird ESR 45.6. Some of these bugs showed evidence of memory corruption and we presume that with enough effort that some of these could be exploited to run arbitrary code (CVE-2016-9893).
