CVE-2017-7252
bcrypt password hashing in Botan before 2.1.0 does not correctly handle passwords with a length between 57 and 72 characters, which makes it easier for attackers to determine the cleartext password.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (0.32%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
