Fix Available:  Yes  Vendor Confirmed:  Yes  
Version(s): prior to 55.0
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 cause denial of service conditions 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 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.

The Developer Tools feature is affected by an XUL injection flaw [CVE-2017-7798].

A use-after-free memory error may occur in WebSockets [CVE-2017-7800].

A use-after-free memory error may occur when recomputing layout for a marquee element during window resizing [CVE-2017-7801].

A use-after-free memory error may occur when an editor DOM node is deleted [CVE-2017-7809].

A use-after-free memory error may occur when reading an image observer during frame reconstruction [CVE-2017-7784].

A use-after-free memory error may occur when manipulating the DOM during the resize event of an image element [CVE-2017-7802].

A buffer overflow may occur when modifying Accessible Rich Internet Applications (ARIA) attributes within the DOM [CVE-2017-7785].

A buffer overflow may occur painting non-displayable SVG [CVE-2017-7786].

A use-after-free memory error may occur when the layer manager is freed too early when rendering specific SVG content [CVE-2017-7806].

Various other memory errors may occur [CVE-2017-7779, CVE-2017-7780].

An out-of-bounds memory read error may occur when applying style rules to pseudo-elements using cached style data [CVE-2017-7753].

A remote user can bypass same-origin policy via iframes and page reloading [CVE-2017-7787].

A remote user can invoke AppCache to hijack a URL in a domain [CVE-2017-7807].

A remote user can create a certificate with a specially crafted object identifier (OID) that, when viewed by the target user, will trigger a buffer overflow and execute arbitrary code [CVE-2017-7792].

A remote user can, in conjunction with a separate vulnerability, cause the WindowsDllDetourPatcher class to bypass memory protections and write arbitrary data to arbitrary memory locations [CVE-2017-7804]. Windows-based systems are affected.

A remote user can spoof the origin of a modal alert via iframe content and the 'data:' protocol [CVE-2017-7791].

A remote user can trigger a cross-origin information leak via a content security policy (CSP) frame-ancestors directive [CVE-2017-7808].

The WindowsDllDetourPatcher function may allocate memory without DEP protections on Windows-based systems [CVE-2017-7782].

A remote user can conduct a man-in-the-middle attack to trigger an elliptic curve point addition error when using mixed Jacobian-affine coordinates and cause the target user to compute an incorrect shared secret [CVE-2017-7781].

A remote user can, via a compromised content process, cause the sandbox broker to truncate files on Linux-based systems [CVE-2017-7794].

A remote user can cause content security policy directives to be ignored in certain cases [CVE-2017-7803].

A user may be able to conduct cross-site scripting attacks via the 'about:webrtc' page [however, the content on the page is supplied by WebRTC usage] [CVE-2017-7799].

A remote user can create a URL containing a specially crafted username and password combination that, when loaded by the target user, will cause the target user's browser to hang or crash [CVE-2017-7783].

A remote user can bypass Content Security Policy (CSP) for sandboxed 'about:srcdoc' iframes [CVE-2017-7788].

A remote server can cause HTTP Strict Transport Security (HSTS) to fail to be enabled for the connection [CVE-2017-7789].

A local user can cause stack memory data to be copied into the crash reporter on Windows-based systems [CVE-2017-7790].

A local user can cause the Windows updater to delete files named 'update.log' [CVE-2017-7796].

A remote user can bypass same-origin restrictions in processing stored header names [CVE-2017-7797].

Amit Sangra, Andi-Bogdan Postelnicu, Andrew McCreight, Andre Bargull, Anne van Kesteren, Antonio Sanso, Arthur Edelstein, Bevis Tseng, Bob Clary, Bryce Van Dyk, Carsten Book, Christian Holler, Dragana Damjanovic, Emilio Cobos Alvarez, Franziskus Kiefer, Fraser Tweedale, Frederik Braun, Gary Kwong, Jann Horn, Jose Maria Acuna, Jun Kokatsu, Kartikaya Gupta, Looben Yang, Masayuki Nakano, Mathias Karlsson, Matt Howell, Muneaki Nishimura, Nils, Oliver Wagner, Philipp, Rhys Enniks, Ronald Crane, Sebastian Hengst, SkyLined, Stephen Fewer, Tristan Bourvon, Tyson Smith, and Xiaoyin Liu reported these vulnerabilities.

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 cause denial of service conditions.

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 remote user can access the target user's cookies (including authentication cookies), if any, associated with an arbitrary site, access data recently submitted by the target user via web form to the site, or take actions on the site acting as the target user.

Solution:   Red Hat has issued a fix for CVE-2017-7753, CVE-2017-7779, CVE-2017-7784, CVE-2017-7785, CVE-2017-7786, CVE-2017-7787, CVE-2017-7791, CVE-2017-7792, CVE-2017-7798, CVE-2017-7800, CVE-2017-7801, CVE-2017-7802, CVE-2017-7803, CVE-2017-7807, and CVE-2017-7809.
