Mandriva Linux Security Advisory MDKSA-2005:200
http://www.mandriva.com/security/
_______________________________________________________________________

Package : apache-mod_auth_shadow
Date : October 27, 2005
Affected: 10.1, 10.2, 2006.0
_______________________________________________________________________

Problem Description:

The mod_auth_shadow module 1.0 through 1.5 and 2.0 for Apache with
AuthShadow enabled uses shadow authentication for all locations that
use the require group directive, even when other authentication
mechanisms are specified, which might allow remote authenticated users
to bypass security restrictions.

This update requires an explicit "AuthShadow on" statement if website
authentication should be checked against /etc/shadow.

The updated packages have been patched to address this issue.
