16 InfoSec Courses, 2 Weeks of Training at SANS Virginia Beach 2017. Save $400 thru June 28.

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.

Title: Microsoft Windows Media Center MCL Vulnerability (MS15-100)
Vendor: Microsoft
Description: Windows Media Center in Microsoft Windows Vista SP2, Windows 7 SP1, Windows 8, and Windows 8.1 allows user-assisted remote attackers to execute arbitrary code via a crafted Media Center link (mcl) file, aka "Windows Media Center RCE Vulnerability."
CVSS v2 Base Score: 9.3 (AV:N/AC:M/Au:N/C:C/I:C/A:C)

ID: CVE-2015-1486
Title: Symantec Endpoint Protection Manager Authentication Bypass

ID: CVE-2015-0816
Title: Mozilla Firefox "resource:// document" Design Error Privilege Escalation Vulnerability
Vendor: Mozilla Firefox
Description: Mozilla Firefox before 37.0, Firefox ESR 31.x before 31.6, and Thunderbird before 31.6 do not properly restrict resource: URLs, which makes it easier for remote attackers to execute arbitrary JavaScript code with chrome privileges by leveraging the ability to bypass the Same Origin Policy, as demonstrated by the resource: URL associated with PDF.js.
