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 obtain potentially sensitive information on the target system. A remote user can spoof URLs. A remote user can conduct cross-site scripting attacks.

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 the Fetch API [CVE-2017-7793].

A use-after-free memory error may occur when manipulating arrays of Accessible Rich Internet Applications (ARIA) elements within containers via the DOM [CVE-2017-7818].

A use-after-free memory error may occur in design mode when image objects are resized [CVE-2017-7819].

A buffer overflow may occur when drawing and validating elements with the ANGLE graphics library [CVE-2017-7824].

A use-after-free memory error may occur during TLS 1.2 exchanges [CVE-2017-7805].

A remote user can create specially crafted content that, when dragged onto the browser tab bar, will open files stored on the target user's system [CVE-2017-7812].

Other memory corruption errors may occur [CVE-2017-7810, CVE-2017-7811].

A remote user can trigger an integer truncation flaw in the JavaScript parser to read data outside of the buffer [CVE-2017-7813].

The content security policy (CSP) sandbox directive may not create a unique origin for a document. A remote user can exploit this to conduct cross-scripting attacks [CVE-2017-7823].

A remote user can bypass phishing and malware protection warnings via 'blob:' and 'data:' URL elements [CVE-2017-7814].

A remote user can cause some Tibetan and Arabic characters in several fonts to be displayed as whitespace, which may allow domain spoofing attacks [CVE-2017-7825]. mac OS X systems are affected.

A remote user can invoke the 'data:' protocol within an iframe to spoof a modal dialog's origin [CVE-2017-7815]. Systems with e10 multiprocess disabled are affected.

A remote user can invoke WebExtensions to load an 'about:' privileged URL [CVE-2017-7816].

A remote user can invoke WebExtensions to download and attempt to open a file of some non-executable file types without user interaction [CVE-2017-7821].

The WebCrypto API AES-GCM implementation accepts 0-length IV. A remote user may be able to exploit this to determine the authentication key in certain cases [CVE-2017-7822].

A remote user may be able to bypass the Xray wrapper mechanism [CVE-2017-7820].

A remote user can spoof the address bar via fullscreen mode [CVE-2017-7817]. Firefox for Android is affected.


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

A remote user can obtain potentially sensitive information on the target system.

A remote user can spoof the address bar and other user interface components.

A remote user can conduct cross-site scripting attacks.

Solution:   The vendor has issued a fix (56.0).
