A constant-time-defeating optimization issue was found in python. This issue occurs when sending a specially crafted request, which could allow an attacker to obtain sensitive information.

Mitigation

As per upstream, either make the accumulator variable result a volatile unsigned char instead of unsigned char or use instead use CRYPTO_memcmp from OpenSSL/BoringSSL when SSL is available as SSL libraries are more secure when it comes to timing based vulnerabilities.
