OpenSSL warned however: "any OpenSSL 3.0 application that verifies X.509 certificates received from untrusted sources should be considered vulnerable. The vulnerabilities affects OpenSSL version 3.0.0 to 3.0.6, with the patch being shipped in version 3.0.7.ĬVE-2022-3602, attributed to "Polar Bear" (aka Sandbo圎scaper) is an "arbitrary 4-byte stack buffer overflow" and had been feared to trigger RCE but this does not appear to be the case. The vulnerabilities have been allocated CVE-2022-3602 and CVE-2022-3786. The library can also be found in a broad array of products, including network devices, embedded systems and container images. It is used in mail servers and VPN protocols to establish encrypted communication channels. OpenSSL is a toolkit for the Transport Layer Security (TLS) protocol formerly known as the Secure Sockets Layer (SSL) protocol. They have been downgraded from "critical" to "high" after being found unlikely to lead to Remote Code Execution (RCE) following external testing in what is a relief for Blue Teams and product owners - and a damp squib for offensive security researchers who had been eagerly anticipating details about the vulnerabilities. There are two new vulnerabilities in OpenSSL - the ubiquitous open source toolkit and cryptographic library used by much enterprise software, as well as by web servers to establish encrypted HTTPS connections. Affect 3.0.0 to 3.0.6, do not provide Remote Code Execution (RCE).
