DESCRIPTION:
A security issue has been reported in MoinMoin, which can be
exploited by malicious users to bypass certain security
restrictions.
The security issue is caused due to an incorrect evaluation of ACL
rules when applied to a group that contains a virtual group (e.g.
"All", "Known", or "Trusted"). This can be exploited to have
incorrect permissions assigned and access restricted content.
Successful exploitation requires that virtual group members exist
within another group.
The security issue is reported in version 1.9.4 and prior.
SOLUTION:
As a workaround the vendor recommends to apply the patch.
