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: Cisco Releases Five Advisories for Various Denial of Service Vulnerabilities
Description: Cisco has released five advisories for various denial of service vulnerabilities that have been identified in various products. Four of the five advisories are rated as high-impact while the fifth, CVE-2016-1363, is rated critical. CVE-2016-1363 manifests due to improperly handling HTTP URL redirects and could allow an unauthenticated, remote attacker to trigger the flaw "by sending a crafted HTTP request to an affected device." This crafted request could cause "a buffer overflow condition" to occur and result in a DoS condition or arbitrary code execution. Cisco has released updated software that addresses this vulnerability as well as the others.
