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 VULNERABILITY RESEARCH TEAM

Title: WordPress XSS Zero-day Vulnerability Disclosed and Patched
Description: A cross-site scripting zero-day vulnerability within WordPress has been disclosed. The issue is in the way comments larger than 64kb are stored into the MySQL database, resulting in malformed HTML. An unauthenticated attacker who leverages this vulnerability and posts a malicious comment could conduct a cross-site scripting attack. WordPress has released an updated version which patches this vulnerability.
Reference:

Snort SID: Detection pending

Title: Security Flaw within YubiKey NEO could allow bypass of PIN Verification
Description: A defect within the YubiKey NEO firmware could potentially allow an attacker to bypass PIN verification and perform security operations. YubiKey firmware version 1.0.9 and below are affected by the security flaw. Yubico is informing users that they do not see "any immediate need for users to upgrade existing deployed products" because "a successful attack requires other privileged operations (such as local root access)". Yubico is offering a free replacement key for users who currently are in possession of a vulnerable one.
