PEAR-Auth: Potential authentication bypass

Background

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

Description

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

Impact

A remote attacker could possibly exploit this vulnerability to bypass the authentication mechanism by injecting specially crafted input to the underlying storage containers.

Workaround

There is no known workaround at this time.

Resolution

All PEAR-Auth users should upgrade to the latest version:

 # emerge --sync
 # emerge --ask --oneshot --verbose ">=dev-php/PEAR-Auth-1.2.4"
