NVD Description
Note: Versions mentioned in the description apply only to the upstream wolfssl package and not the wolfssl package as distributed by Ubuntu.
A specially crafted x509 certificate can cause a single out of bounds byte overwrite in wolfSSL through 3.10.2 resulting in potential certificate validation vulnerabilities, denial of service and possible remote code execution. In order to trigger this vulnerability, the attacker needs to supply a malicious x509 certificate to either a server or a client application using this library.
