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 type confusion error may occur in nsDisplayList::HitTest() [CVE-2016-5263].

A heap overflow may occur in the ClearKey Content Decryption Module (CDM) [CVE-2016-2837].

An integer overflow may occur in WebSocketChannel [CVE-2016-5261].

A use-after-free memory error may occur in nsNodeUtils::NativeAnonymousChildListChange() in the processing of SVG elements [CVE-2016-5264].

A use-after-free memory error may occur in CanonicalizeXPCOMParticipant() [CVE-2016-5259].

A use-after-free memory error may occur in WebRTC [CVE-2016-5258].

A use-after-free memory error may occur in nsXULPopupManager::KeyDown() [CVE-2016-5254].

A remote user can cause scripting code to execute inside a sandboxed IFRAME that does not permit scripts [CVE-2016-5262].

A remote server can keep a connection open to a target user that has previously requested the favicon after the target user has closed the page to track the target user's IP address as it subsequently changes [CVE-2016-2830].

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].

A remote user can pass text as parameters to certain 'about:' URLs to spoof browser content [CVE-2016-5268].
