CVE-2024-45158

An issue was discovered in Mbed TLS 3.6 before 3.6.1. A stack buffer overflow in mbedtlsecdsadertoraw and mbedtlsecdsarawtoder can occur when the bits parameter is larger than the largest supported curve. In some configurations with PSA disabled, all values of bits are affected. This never happen...
