Description:   Multiple vulnerabilities were reported in Mozilla Firefox. A remote user can cause arbitrary code to be executed on the target user's system. A remote user can gain elevated privileges. A remote user can bypass security controls on the target system. A remote user can obtain potentially sensitive information on the target system. A remote user can spoof URLs.

A remote user can create specially crafted content that, when loaded by the target user, will execute arbitrary code on the target user's system.

A use-after-free memory error may occur in XSL when processing XSLT documents [CVE-2017-5376].

A memory corruption error may occur in Skia when using transforms to make gradients [CVE-2017-5377].

A use-after-free memory error may occur in Web Animations when interacting with cycle collection [CVE-2017-5379].

A use-after-free memory error may occur in processing SVG content [CVE-2017-5380].

A use-after-free memory error may occur in Media Decoder [CVE-2017-5396].

A remote user can exploit a proxy object thread reference flaw to potentially execute arbitrary code [CVE-2017-5392]. Android systems are affected.

Various memory corruption errors may occur [CVE-2017-5373, CVE-2017-5374].

A remote user can spoof URLs using certain unicode glyphs for alternative hyphens and quotes [CVE-2017-5383].
