Description

An exploitable free of a stack pointer vulnerability exists in the x509 certificate parsing code of ARM mbed TLS before 1.3.19, 2.x before 2.1.7, and 2.4.x before 2.4.2. A specially crafted x509 certificate, when parsed by mbed TLS library, can cause an invalid free of a stack pointer leading to a potential remote code execution. In order to exploit this vulnerability, an attacker can act as either a client or a server on a network to deliver malicious x509 certificates to vulnerable applications.

Affected configurations

• trustedfirmware mbed tls (<= 1.3.18) • trustedfirmware mbed tls 2.0.0 • trustedfirmware mbed tls 2.1.0 • trustedfirmware mbed tls 2.1.1 • trustedfirmware mbed tls 2.1.2 • trustedfirmware mbed tls 2.1.3 • trustedfirmware mbed tls 2.1.4 • trustedfirmware mbed tls 2.1.5 • trustedfirmware mbed tls 2.1.6 • trustedfirmware mbed tls 2.4.0
