Vulnerability Spotlight: Randombit Botan Library X509 Certificate Validation Bypass Vulnerability
Summary: Aleksandar Nikolic of Cisco Talos discovered TALOS-2017-0294 (CVE-2017-2801), an X509 certificate validation bypass in the Randombit Botan Library that lets crafted certificates pass or fail equality checks depending on the contents of X509 distinguished names and the target application's memory layout. Talos says the flaw can fool systems into connecting to unauthorized computers, enabling man-in-the-middle attacks or connections to a malicious server.
What you should know: A certificate check that returns the wrong answer based on memory layout undermines the one control most teams assume is absolute when deciding which server to trust.
