KETAMINE: SecureRandom() Weakness
Posted Apr 13, 2018

A significant number of past and current cryptocurrency products contain a JavaScript class named SecureRandom(), containing both entropy collection and a PRNG. The entropy collection and the RNG itself are both deficient to the degree that key material can be recovered by a third party with medium complexity.

Red Hat Security Advisory 2018-0380-01

Authored by Red Hat | Site access.redhat.com

Red Hat Security Advisory 2018-0380-01 - Red Hat CloudForms Management Engine delivers the insight, control, and automation needed to address the challenges of managing virtual environments. CloudForms Management Engine is built on Ruby on Rails, a model-view-controller framework for web application development. Action Pack implements the controller and the view components. Security Fix: A flaw was found in CloudForms in the self-service UI snapshot feature where the name field is not properly sanitized for HTML and JavaScript input. An attacker could use this flaw to execute a stored XSS attack on an application administrator using CloudForms. Please note that CSP prevents exploitation of this XSS however not all browsers support CSP.

Chakra CFG Bypass With leafInterpreterFrame
Posted Dec 5, 2017
Authored by Ivan Fratric, Google Security Research

Chakra suffers from a CFG bypass with leafInterpreterFrame. Every JavaScript variable in Chakra (except a tagged int) is a pointer. From this pointer, using an arbitrary read, it is possible to follow a chain of pointers and end up with a pointer to the native stack. This allows disclosing the stack location and subsequently overwriting a return address on the stack leading to CFG bypass.

Ubuntu Security Notice 3477-3 - USN-3477-1 fixed vulnerabilities in Firefox. The update introduced various minor regressions. This update fixes the problems. Multiple security issues were discovered in Firefox. If a user were tricked in to opening a specially crafted website, an attacker could potentially exploit these to cause a denial of service, read uninitialized memory, obtain sensitive information, bypass same-origin restrictions, bypass CSP protections, bypass mixed content blocking, spoof the addressbar, or execute arbitrary code. It was discovered that javascript: URLs pasted in to the addressbar would be executed instead of being blocked in some circumstances. If a user were tricked in to copying a specially crafted URL in to the addressbar, an attacker could potentially exploit this to conduct cross-site scripting attacks. It was discovered that exported bookmarks do not strip script elements from user-supplied tags. If a user were tricked in to adding specially crafted tags to bookmarks, exporting them and then opening the resulting HTML file, an attacker could potentially exploit this to conduct cross-site scripting attacks. Various other issues were also addressed.

Red Hat Security Advisory 2017-3002-01 - Node.js is a platform built on Chrome's JavaScript runtime for easily building fast, scalable network applications. 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 later upstream version: rh-nodejs4-nodejs. Security Fix: It was found that Node.js was using a non-randomized seed when populating hash tables. An attacker, able to supply a large number of inputs, could send specially crafted entries to the Node.js application, maximizing hash collisions to trigger an excessive amount of CPU usage, resulting in a denial of service.

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.
