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.
