Synopsis
========
PEAR-Auth did not correctly verify data passed to the DB and LDAP
containers, thus allowing to inject false credentials to bypass the
authentication.
Background

PEAR-Auth is a PEAR package that provides methods to create a PHP based
authentication system.
Affected packages
=================

Description
===========
Matt Van Gundy discovered that PEAR-Auth did not correctly validate
data passed to the DB and LDAP containers.
Impact

the authentication mechanism by injecting specially crafted input to
the underlying storage containers.
Workaround
