@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: glibc Project Releases Patch to Address Critical Buffer Overflow Flaw in getaddrinfo() Description: The glibc project has released a security advisory to address CVE-2015-7547, a stack-based buffer overflow flaw which was discovered by Google and Red Hat security researchers. This vulnerability manifests as a flaw in the glibc client-side DNS resolver where mismanagement of buffers in memory could potentially result in remote code execution. Red Hat researchers note that "it should be possible to write correctly formed DNS responses with attacker controlled payloads that will penetrate a DNS cache hierarchy and therefore allow attackers to exploit machines behind such caches." Google researchers also note that all glibc versions since 2.9 are affected by this flaw. The glibc project has released a patch to address this vulnerability. Reference: https://sourceware.org/ml/libc-alpha/2016-02/msg00416.html Snort SID: Detection pending
Title: Cisco Releases Security Advisory to Address Buffer Overflow Flaw
in ASA Software
Description: Cisco has released a critical security advisory to address
CVE-2016-1287, a buffer overflow vulnerability in Cisco ASA software.
CVE-2016-1287 manifests as a result of the system improperly handling
fragmented IKEv1/v2 payloads, potentially resulting in remote code
execution. Note that "[t]his vulnerability affects systems configured
in routed firewall mode only and in single or multiple context mode."
Additionally, "only traffic directed to the affected system can be used
to exploit this vulnerability." Cisco has released an update to address
this flaw.

Snort SID: 36903, released Nov 2015
Title: Blue Frost Security Releases Advisory Over FireEye Detection Evasion That Could Lead Whitelisting Arbitrary Malware Description: Blue Frost Security has released an advisory discussing a vulnerability in FireEye Operating System (FEOS) that has been patched. The flaw in question manifests as an "analysis engine evasion" that could allow an attacker to bypass and evade "FireEye's virtualization-based dynamic analysis on Windows and add arbitrary binaries to the internal whitelist of binaries." FireEye has released a fix for this issue as 2015-10-21. Reference: https://labs.bluefrostsecurity.de/advisories/bfs-sa-2016-001/
Title: VMware Reissues Patch for vCenter Server Due to Patch for
CVE-2015-2342 Being Incomplete
Description: VMware has reissued a patch for vCenter Server after
discovering that the patch addressing CVE-2015-2342 was incomplete.
CVE-2015-2342 is a remote code execution vulnerability within the
vCenter Server JMX RMI service which manifests due to an insecure
configuration of the JMX RMI service. VMware notes that Windows Firewall
can mitigate the remote code execution vulnerability on systems where
vCenter Server Windows is installed, but will not mitigate the local
privilege escalation vulnerability. The reissued patched is available
from VMware Knowledge Base (KB) article 2144428.
