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

<description>
|
|
<p>
|
|
Steve Rigler discovered that pam_ldap does not correctly handle
|
|
"PasswordPolicyResponse" control responses from an LDAP directory. This
|
|
causes the pam_authenticate() function to always succeed, even if the
|
|
previous authentication failed.
|
|
</p>
|
|
</description>
|
|
<impact type="low">
|
|
<p>
|
|
A locked user may exploit this vulnerability to bypass the LDAP
|
|
authentication mechanism, possibly gaining unauthorized access to the
|
|
system.
|
|
</p>
|
|
</impact>
|
|
<workaround>
|
|
<p>
|
|
There is no known workaround at this time.
|
|
</p>
|
|
</workaround>
|
|
<resolution>
|
|
<p>
|
|
All pam_ldap users should upgrade to the latest version:
|
|
</p>
|
|
<code>
|
|
# emerge --sync
|
|
# emerge --ask --oneshot --verbose ">=sys-auth/pam_ldap-183"</code>
|
