![]() Ĭ/C++ based software (since OpenSSL v3 packages maybe included).Ĭontainer images built with vulnerable Linux versions.Linux operating systems such as Ubuntu 22.04 LTS, MacOS Ventura, Fedora 36, and others It is worth noticing if you are handling the following: If your system contains OpenSSL versions from 3.0.0 to 3.0.6, you are likely to be more vulnerable. Am I vulnerable to the OpenSSL vulnerability and how to fix it? OpenSSL libraries 3.0.6 and lower versions are affected here. ![]() Quick details on the vulnerability by OpenSSL: How can an attacker exploit you with the latest OpenSSL vulnerability?Īn attacker can redirect the victim to the malicious TLS server which contains malicious certificates generated and verified by them which in turn triggers the vulnerability.įor your notice: OpenSSL version 3 and SSLv3 are not the same. The servers can also be susceptible to the attack through the TLS Client, that could override the CA signing requirements since the client certificates are typically not required to be signed by a trustworthy CA. It majorly affects the client (aka the users) - being the certificate verified on the client side. And it can be used to execute RCE (Remote Code Execution) through a malicious TLS certificate, which is signed by a trusted CA (Certificate Authority). Released on October 25, 2022, it is a buffer overflow vulnerability found in the X.509 certification verification (TLS certificate verification code) of the OpenSSL library versions 3.0.6 and lesser.
