ARM Mbedtls x509 ECDSA invalid public key Remote Code Execution Vulnerability

Summary An exploitable free of a stack pointer vulnerability exists in the x509 certificate parsing code of ARM mbedTLS 2.4.0. A specially crafted x509 certificate, when parsed by mbedTLS library, can cause an invalid free of a stack pointer leading to a potential remote code execution. In order ...
