Description
If auth_username_chars is empty, it is possible to inject arbitrary LDAP filter to Dovecot-s LDAP authentication. This leads to potentially bypassing restrictions and allows probing of LDAP structure. Do not clear out auth_username_chars, or install fixed version. No publicly available exploits are known.
