Описание
The (1) make_nonce, (2) generate_nonce, and (3) generate_verifier functions in SimpleGeo python-oauth2 uses weak random numbers to generate nonces, which makes it easier for remote attackers to guess the nonce via a brute force attack.
It was found that python-oauth2 did not properly generate random values for use in nonces. An attacker able to capture network traffic of a website using OAuth2 authentication could use this flaw to conduct replay attacks against that website.
