Microsoft Edge Partial Page Loading Memory Corruption
Posted Sep 19, 2017
Authored by Ivan Fratric, Google Security Research

There is a security issue in Microsoft Edge related to how HTML documents are loaded. If Edge displays a HTML document from a slow HTTP server, it is possible that a part of the document is going to be rendered before the server has finished sending the document. It is also possible that some JavaScript code is going to trigger. By making DOM modifications before the document had a chance of fully loading, followed by another set of DOM modifications after the page has been loaded, it is possible to trigger memory corruption that could possibly lead to an exploitable condition.

Nitro Pro PDF Reader 11.0.3.173 Remote Code Execution
Posted Aug 2, 2017
Authored by mr_me, sinn3r, Brendan Coles | Site metasploit.com

This Metasploit module exploits an unsafe Javascript API implemented in Nitro and Nitro Pro PDF Reader version 11. The saveAs() Javascript API function allows for writing arbitrary files to the file system. Additionally, the launchURL() function allows an attacker to execute local files on the file system and bypass the security dialog Note: This is 100% reliable.

If a user were tricked in to opening a specially crafted website in a browsing context, an attacker could potentially exploit this to conduct cross-site scripting attacks. Various other issues were also addressed.

Node.js uses an event-driven, non-blocking I/O model that makes it lightweight and efficient, perfect for data-intensive real-time applications that run across distributed devices. The following packages have been upgraded to a newer upstream version: rh-nodejs4-nodejs, rh-nodejs4-http-parser. Security Fix: It was found that Node.js' tls.checkServerIdentity() function did not properly validate server certificates containing wildcards. A malicious TLS server could use this flaw to get a specially crafted certificate accepted by a Node.js TLS client.

Microsoft Edge FillFromPrototypes Type Confusion
Posted Nov 18, 2016
Authored by Google Security Research, natashenka

JavascriptArray::FillFromPrototypes is a method that is used by several Javascript functions available in the browser to set the native elements of an array to the values provide by its prototype. This function calls JavascriptArray::ForEachOwnMissingArrayIndexOfObject with the prototype of the object as a parameter, and if the prototype of the object is an array, it assumes that it is a Var array. While arrays are generally converted to var arrays if they are set as an object's prototype, if an object's prototype is a Proxy object, it can return a parent prototype that is a native int array. This can lead to type confusing, allowing an integer to be treated as an absolute pointer, when JavascriptArray::FillFromPrototypes is called.
