Description Andrej Nemec 2017-04-11 09:34:55 UTC

Botan’s implementation of X.509 name comparisons had a flaw which could result in an out of bound memory read while processing a specially formed DN. This could potentially be exploited for information disclosure or denial of service, or result in incorrect validation results.
