Newsletters: @RISK


@RISK provides a reliable weekly summary of (1) newly discovered attack vectors, (2) vulnerabilities with active new exploits, (3) insightful explanations of how recent attacks worked, and other valuable data

A key purpose of the @RISK is to provide the data that will ensure that the 20 Critical Controls (the US and UK benchmark for effective protection of networked systems) continue to be the most effective defenses for all known attack vectors. But since it is also valuable for security practitioners, SANS is making it available to the 145,000 security practitioners who have completed SANS security training and others at their organizations who hope to stay current with the offensive methods in use.

SELECTED BY THE TALOS SECURITY INTELLIGENCE AND RESEARCH GROUP

Title: Adobe Patches Vulnerabilities Under Active Exploitation in Monthly Flash Player Security Bulletin
Description: Adobe has released their monthly Flash Player security bulletin to address vulnerabilities, one of which is currently under active exploitation in the wild. CVE-2016-4117 is a type-confusion vulnerability that was originally reported to Adobe by FireEye. 24 other security vulnerabilities were also addressed in the bulletin with the the majority of them being use-after-free flaws and memory corruption flaws that could lead to arbitrary code execution. Users are advised to disable or remove Flash from their browser if it's not necessary and to otherwise patch as soon as possible if removal is not an option.

Title: 7-Zip Vulnerabilities Leading to Arbitrary Code Execution Patched
Description: Marcin Noga of the Talos Group at Cisco has identified two major vulnerabilities in 7-Zip, an open-source file archiving application which is used in various applications. One of the vulnerabilities, CVE-2016-2335, is a out-of-bounds read vulnerability which, if exploited, could lead to arbitrary code execution. The other vulnerability, CVE-2016-2334 is a heap overflow vulnerability. Igor Pavlov, the maintainer of 7-Zip, has release an updated version of 7-Zip to address these security flaws.
