Last Day to Save $400 on 4-6 Day Courses at SANS Cyber Defense Initiative 2017!

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.

NOTABLE RECENT SECURITY ISSUES
SELECTED BY THE TALOS SECURITY INTELLIGENCE AND RESEARCH GROUP

Title: Microsoft Releases Monthly Security Bulletins for October 2016
Description: Microsoft has released 10 bulletins for October to address 37 newly disclosed security flaws. Five bulletins rated critical and address vulnerabilities in Edge, Graphics Component, Internet Explorer, Video Control, and Adobe Flash Player. Four bulletins are rated important and address flaws in Office, Windows Diagnostic Hub, Windows Kernel-Mode Drivers, and Windows Registry. One bulletin is rated moderate and addresses a flaw in Microsoft Internet Messaging API.
Reference: https://technet.microsoft.com/en-us/library/security/ms16-oct.aspx
Snort SID: 40364-40381, 40383-40405, 40408-40412, 40418-40428

Title: Adobe Releases Security Bulletin for Flash Player, PDF Reader, and Acrobat
Description: Adobe has released security bulletins for Flash Player, PDF Reader, and Acrobat to address a multitude of vulnerabilities. The Flash Player bulletin remediates 12 vulnerabilities that could be used to achieve remote code execution. The PDF Reader and Acrobat security bulletin remediates 71 vulnerabilities that could be also be used to achieve arbitrary code execution or bypass security features or restrictions. The vast majority of the vulnerabilities addressed in Flash Player, PDF Reader, and Acrobat are memory corruption flaws, use-after-free flaws, heap buffer overflow flaws, and type confusion flaws. Users who have Flash Player installed should consider uninstalling it if it's not business critical. All users should otherwise immediately patch Flash Player, PDF Reader, and Acrobat if they are installed.

Snort SID: Detection pending release of vulnerability information

Title: Cisco Releases Critical Security Advisories for Nexus Family of Products
Description: Cisco has released two critical security advisories for its Nexus family of products that could be exploited to achieve code execution or bypass security restrictions on the targeted device. The first advisory addresses CVE-2016-1453, a buffer overflow vulnerability that manifests due to "incomplete input validation performed on the size of OTV packet header parameters." The other advisory addresses CVE-2015-0721, a security feature bypass vulnerability that manifests as a failure to enforce "authentication, authorization, and accounting restrictions," potentially allowing an authenticated adversary to "execute commands on the device command-line interface (CLI) that should be restricted to a different privileged user role." Cisco has released a software update that corrects these issues.
