Security teams should apply vendor patches immediately to protect their Linux, OpenBSD, NetBSD, FreeBSD and Solaris infrastructure from The Stack Clash vulnerability (also see the security advisory). To help in that effort, this blog post describes a new built-in Qualys AssetView dashboard to visualize The Stack Clash and quickly identify vulnerable assets in your organization.
What is the Stack Clash?
The Stack Clash is a vulnerability in the memory management of several operating systems. It affects Linux, OpenBSD, NetBSD, FreeBSD and Solaris, on i386 and amd64. It can be exploited by attackers to corrupt memory and execute arbitrary code.
Qualys researchers discovered this vulnerability and developed seven exploits and seven proofs of concept for this weakness, then worked closely with vendors to develop patches. As a result we are releasing this advisory today as a coordinated effort, and patches for all distributions are available June 19, 2017. We strongly recommend that users place a high priority on patching these vulnerabilities immediately.
