Synopsis
========

A flaw in phpLDAPadmin may allow attackers to bypass security
restrictions and connect anonymously.

Background
==========

phpLDAPadmin is a web-based LDAP client allowing to easily manage LDAP
servers.

Affected packages
=================

-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 net-nds/phpldapadmin lt; 0.9.7_alpha6 gt;= 0.9.7_alpha6

Description
===========

Alexander Gerasiov discovered a flaw in login.php preventing the
application from validating whether anonymous bind has been disabled in
the target LDAP server configuration.

Impact
======

Anonymous users can access the LDAP server, even if the
"disable_anon_bind" parameter was explicitly set to avoid this.

Workaround
==========

There is no known workaround at this time.

Resolution
==========

All phpLDAPadmin users should upgrade to the latest version:

# emerge --sync
# emerge --ask --oneshot --verbose "gt;=net-nds/phpldapadmin-0.9.7_alpha6"
