pam_ldap is a Pluggable Authentication Module which allows
|
|
authentication against LDAP directories.

<description>
|
|
<p>
|
|
When a pam_ldap client attempts to authenticate against an LDAP
|
|
server that omits the optional error value from the
|
|
PasswordPolicyResponseValue, the authentication attempt will always
|
|
succeed.
|
|
</p>
|
|
</description>
|
|
<impact type="normal">
|
|
<p>
|
|
A remote attacker may exploit this vulnerability to bypass the
|
|
LDAP authentication mechanism, gaining access to the system possibly
|
|
with elevated privileges.
|
|
</p>
|
|
</impact>
|
|
<workaround>
|
|
<p>
|
|
There is no known workaround at this time.
