@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.

Title: Arbitrary Code Execution Flaw in Ubuntu Desktop Crash Reporter Identified and Patched
Description: An arbitrary code execution flaw in the Ubuntu Desktop crash reporter has been identified by an independent security researcher. These bugs, identified as CVE-2016-9949 and CVE-2016-9950, manifest as a result of Ubuntu attempting to determine the file type of a crash report to open the crash report handler application. A user who opens a specifically formatted crash report file could allow an attacker to achieve arbitrary code execution on the targeted system. Ubuntu versions 12.10 and later are known to be affected. Ubuntu has addressed the vulnerability by releasing an update.

Title: Command Injection Vulnerability in Nagios Core Identified and Fixed
Description: A command injection vulnerability in Nagios Core has been identified by a researcher at Legal Hackers. This particular vulnerability, identified as CVE-2016-9565, manifests in the front-end RSS feed reader component MagpieRSS. This flaw could be exploited if the Nagios server attempts to load an RSS feed from a server impersonating the feed server. Golunski, the researcher who identified this flaw, notes that this vulnerability is notable as Nagios server installations tend to have visibility into many aspects of an organization and could allow an attacker to gain visibility and more laterally within a network. Nagios has released an update, version 4.2.4, which addresses the flaw.
