CVE-2016-5289 [CRITICAL] Firefox vulnerabilities
Title: Firefox vulnerabilities
Summary: Firefox could be made to crash or run programs as your login if it
opened a malicious website.
Christian Holler, Andrew McCreight, Dan Minor, Tyson Smith, Jon Coppeard,
Jan-Ivar Bruaroey, Jesse Ruderman, Markus Stange, Olli Pettay, Ehsan
Akhgari, Gary Kwong, Tooru Fujisawa, and Randell Jesup discovered multiple
memory safety issues in Firefox. If a user were tricked in to opening a
specially crafted website, an attacker could potentially exploit these to
cause a denial of service via application crash, or execute arbitrary
code. (CVE-2016-5289, CVE-2016-5290)
A same-origin policy bypass was discovered with local HTML files in some
circumstances. An attacker could potentially exploit this to obtain
sensitive information. (CVE-2016-5291)

Discussion:
This fixes some integer overflows, a double free and more. So marking s-s for now.
---
FWIW I've explicitly avoided updating to the latest expat versions as they've tend to introduce more CVE's than they fix. We keep a much trimmed down (and modified) version of 2.0.0 in tree, it would be interesting to see what overlap there is and maybe just cherry-pick changes that are relevant to us.
---
I've started looking over the differences. I'll attach some patches with some no-brainers and then we can decide on the rest.
