Synopsis

========

 

A vulnerability in DBMail could allow for passwordless login to any

account under certain configurations.

 

Background

==========

 

DBMail is a mail storage and retrieval daemon that uses SQL databases

as its data store. IMAP and POP3 can be used to retrieve mails from the

database.

 

Affected packages

=================

 

-------------------------------------------------------------------

Package / Vulnerable / Unaffected

-------------------------------------------------------------------

1 net-mail/dbmail < 2.2.9 >= 2.2.9

 

Description

===========

 

A vulnerability in DBMail's authldap module when used in conjunction

with an Active Directory server has been reported by vugluskr. When

passing a zero length password to the module, it tries to bind

anonymously to the LDAP server. If the LDAP server allows anonymous

binds, this bind succeeds and results in a successful authentication to

DBMail.

 

Impact

======

 

By passing an empty password string to the server, an attacker could be

able to log in to any account.

 

Workaround

==========

 

There is no known workaround at this time.

 

Resolution

==========

 

All DBMail users should upgrade to the latest version:

 

# emerge --sync

# emerge --ask --oneshot --verbose ">=net-mail/dbmail-2.2.9"
