Mozilla security researcher moz_bug_r_a4 reported a method to use browser navigations through history to load a website with that page"s baseURI property pointing to that of another site instead of the seemingly loaded one. The user will continue to see the incorrect site in the addressbar of the browser. This allows for a cross-site scripting (XSS) attack or the theft of data through a phishing ...
Security researcher Mariusz Mlynski discovered an issue where sites that have been given notification permissions by a user can bypass security checks on source components for the Web Notification API. This allows for script to be run in a privileged context through notifications, leading to arbitrary code execution on these sites.
Security researcher Juho Nurminen reported that on Firefox for Android, when the addressbar has been scrolled off screen, an attacker can prevent it from rendering again through the use of script interacting DOM events. This allows an attacker to present a fake addressbar to the user, possibly leading to successful phishing attacks.
Using the Address Sanitizer tool, security researcher Abhishek Arya (Inferno) of the Google Chrome Security Team found a use-after-free in the Text Track Manager while processing HTML video. This was caused by inconsistent garbage collection of Text Track Manager variables and results in a potentially exploitable crash.
Security researcher Abhishek Arya (Inferno) of the Google Chrome Security Team used the Address Sanitizer tool to discover a buffer overflow when a script uses a non-XBL object as an XBL object because the XBL status of the object is not properly validated. The resulting memory corruption is potentially exploitable.
Security researcher Abhishek Arya (Inferno) of the Google Chrome Security Team used the Address Sanitizer tool to discover a fixed offset out of bounds read issue while decoding specifically formatted JPG format images. This causes a non-exploitable crash.
Mozilla developers and community identified identified and fixed several memory safety bugs in the browser engine used in Firefox and other Mozilla-based products. Some of these bugs showed evidence of memory corruption under certain circumstances, and we presume that with enough effort at least some of these could be exploited to run arbitrary code.
The host is missing a high severity security update according to Google advisory. The update is required to fix multiple unspecified vulnerabilities. The flaws are present in the application, which fails to properly handle crafted data. Successful exploitation could allow attackers to crash the service.
