Description

The myuser_delete function in libathemecore/account.c in Atheme 5.x before 5.2.7 6.x before 6.0.10 and 7.x before 7.0.0-beta2 does not properly clean up CertFP entries when a user is deleted which allows remote attackers to access a different user account or cause a denial of service (daemon crash) via a login as a deleted user.
