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 modify files on the target system. 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 content. A local user can gain elevated privileges on the target system.

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.

Various memory corruption errors may occur [CVE-2016-2835, CVE-2016-2836].

A heap overflow may occur in nsBidi::BracketData::AddOpening() [CVE-2016-2838].

A stack underflow may occur in mozilla::gfx::BasePoint4d() in the processing of clipping regions in 2D graphics [CVE-2016-5252].

A remote user can cause the Cairo graphics layer on Linux-based systems (via LibAV) to crash [CVE-2016-2839].

A remote user can use non-ASCII and emjoi characters in 'data:' URLs to spoof URLs in the location bar [CVE-2016-5251].

In certain cases, a local user can exploit a flaw in the Updater on Windows-based systems to potentially gain elevated privileges [CVE-2016-5253].

In certain cases, Firefox session restore data may contain plain text passwords [CVE-2016-5260].

A user can create a specially crafted HTML file and shortcut that, when saved to the same directory on the target user's system and then loaded by the target user, will bypass same origin policy and access potentially sensitive information on the target user's system [CVE-2016-5265].

A remote user can exploit a filtering flaw in the processing of URIs that are dragged by the target user from a web page rendered in Firefox to external software (e.g., local file manager) to modify files on the target user's system [CVE-2016-5266].

A remote user can spoof the addressbar in Firefox for Android via right-to-left character sets combined with left-to-right characters [CVE-2016-5267].
