Summary
Observable Timing Discrepancy in totp-rs
Details
Impact
Token comparison was not constant time, and could theorically be used to guess value of an TOTP token, and thus reuse it in the same time window. The attacker would have to know the password beforehand nonetheless.
Patches
Library now used constant-time comparison.
Workarounds
No.
