(CVE-2017-5383) - WebExtension scripts can use the 'data:' protocol to affect pages loaded by other web extensions using this protocol, leading to potential data disclosure or privilege escalation in affected extensions. (CVE-2017-5380) - URLs containing certain unicode glyphs for alternative hyphens and quotes do not properly trigger punycode display, allowing for domain name spoofing attacks in the location bar. (CVE-2017-5378) - A potential use-after-free found through fuzzing during DOM manipulation of SVG content.

This allows for pointer leaks because an object's address can be discovered through hash codes, and also allows for data leakage of an object's content using these hash codes. (CVE-2017-5375) - Use-after-free while manipulating XSL in XSLT documents (CVE-2017-5376) - Hashed codes of JavaScript objects are shared between pages. (CVE-2017-5373) - JIT code allocation can allow for a bypass of ASLR and DEP protections leading to potential memory corruption attacks.

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. It is, therefore, affected by the following vulnerabilities : - Mozilla developers and community members Christian Holler, Gary Kwong, Andre Bargull, Jan de Mooij, Tom Schuster, and Oriol reported memory safety bugs present in Firefox 50.1 and Firefox ESR 45.6.
