### [CVE-2019-17185](https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2019-17185) ![](https://img.shields.io/static/v1?label=Product&message=n%2Fa&color=blue) ![](https://img.shields.io/static/v1?label=Version&message=n%2Fa&color=blue) ![](https://img.shields.io/static/v1?label=Vulnerability&message=n%2Fa&color=brighgreen) ### Description In FreeRADIUS 3.0.x before 3.0.20, the EAP-pwd module used a global OpenSSL BN_CTX instance to handle all handshakes. This mean multiple threads use the same BN_CTX instance concurrently, resulting in crashes when concurrent EAP-pwd handshakes are initiated. This can be abused by an adversary as a Denial-of-Service (DoS) attack. ### POC #### Reference No PoCs from references. #### Github - https://github.com/ARPSyndicate/cvemon - https://github.com/chnzzh/OpenSSL-CVE-lib
