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: Flaw within QEMU's virtual Floppy Disk Controller could allow VM
escape (a.k.a. VENOM)
Description: CrowdStrike researchers have discovered a vulnerability within QEMU that could allow attacker to escape the confines of a VM and execute arbitrary code the host. In order to exploit this vulnerability (which can be identified as CVE-2015-3456), an attack would need to have administrative/root privileges on the affected host. Affected vendors are aware of this vulnerability and have released advisories and patches.
Reference: http://venom.crowdstrike.com/

Title: Command Injection Vulnerability in Multiple Cisco TelePresence
Products Patched
Description: Cisco has issued an security advisory for several of its TelePresence products. The vulnerability, identified by CVE-2015-0713, is a flaw within the web framework of that "could allow an authenticated, remote attacker to inject arbitrary commands that are executed with the privileges of the root user." Cisco has released a software updates for affected products.
