Name of the Vulnerable Software and Affected Versions Mbed TLS versions 3.2.x through 3.4.x

Description The issue is related to a buffer overflow in Mbed TLS, which can lead to remote code execution. This occurs due to a heap-based buffer overflow vulnerability in the implementation of TLS and SSL protocols. An attacker can exploit this by sending specially crafted open ECDH or FFDH keys, allowing them to execute arbitrary code remotely.

Recommendations For Mbed TLS versions 3.2.x through 3.4.x, update to version 3.5 or later to resolve the issue. As a temporary workaround, consider restricting the use of ECDH and FFDH keys in the affected Mbed TLS versions until a patch is available.
