OpenVPN -- potential side-channel/timing attack when comparing HMACs
The OpenVPN project reports: OpenVPN 2.3.0 and earlier running in UDP mode are subject to chosen ciphertext injection due to a non-constant-time HMAC comparison function...

Timing attack vector for remember me token
The current rememberme token verification process leaves the application open to a timing attack. Since the default is for the token to be stored as a cookie and for cookies to be encrypted, an attacker would have to know the application secret to exploit this. However, should a custom guard be...
