A vulnerability exists where the caret ("^") character is improperly escaped constructing some URIs due to it being used as a separator, allowing for possible spoofing of origin attributes.
A vulnerability exists where if a user opens a locally saved HTML file, this file can use file: URIs to access other files in the same directory or sub-directories if the names are known or guessed. The Fetch API can then be used to read the contents of any files stored in these directories and they may uploaded to a server. Luigi Gubello demonstrated that in combination with a popular Android messaging app, if a malicious HTML attachment is sent to a user and they opened that attachment in Firefox, due to that app's predictable pattern for locally-saved file names, it is possible to read attachments the victim received from other correspondents.
A bug in the standard library ScalarMult implementation of curve P-256 for amd64 architectures in Go before 1.7.6 and 1.8.x before 1.8.2 causes incorrect results to be generated for specific input points. An adaptive attack can be mounted to progressively extract the scalar input to ScalarMult by submitting crafted points and observing failures to the derive correct output. This leads to a full key recovery attack against static ECDH, as used in popular JWT libraries.
The Extensions subsystem in Google Chrome before 50.0.2661.75 incorrectly relies on GetOrigin method calls for origin comparisons, which allows remote attackers to bypass the Same Origin Policy and obtain sensitive information via a crafted extension.
The WebContentsImpl::FocusLocationBarByDefault function in content/browser/webcontents/webcontentsimpl.cc in Google Chrome before 50.0.2661.75 mishandles focus for certain about:blank pages, which allows remote attackers to spoof the address bar via a crafted URL.
Memory leak in libstagefright in Mozilla Firefox before 45.0 and Firefox ESR 38.x before 38.7 allows remote attackers to cause a denial of service (memory consumption) via an MPEG-4 file that triggers a delete operation on an array.
Mozilla Firefox before 45.0 allows remote attackers to bypass the Same Origin Policy and obtain sensitive information by reading a Content Security Policy (CSP) violation report that contains path information associated with an IFRAME element.
