Gentoo Linux Security Advisory GLSA 200804-24

                                         http://security.gentoo.org/

Severity: Low
Title: DBmail: Data disclosure
Date: April 18, 2008
Bugs: #218154
ID: 200804-24

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"
