Exploitation vector: Remote access
Exploit availability: No public exploit available
Vulnerable software:
mbed TLS
Software vendor:
ARM

Description

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to a boundary error in TLS handshake parsing with ECDH. A remote attacker can send specially crafted input to the application, trigger a heap-based buffer overflow and execute arbitrary code on the target system.

A TLS 1.2 server configured with MBEDTLS_USE_PSA_CRYPTO and with support for a cipher suite using ECDH and a signature is vulnerable.
