Description Laura Pardo 2018-01-12 20:49:16 UTC 
A flaw was found in rack-protection. Versions prior to 2.0.0.rc3 of the package are vulnerable to Timing Attack due to time-variable comparison of signatures. A malicious user can guess a valid signature one char at a time by considering the time it takes a signature validation to fail.
