                Linux-Mandrake Security Update Advisory


Package name:           Zope
Date:                   September 1st, 2000
Advisory ID:            MDKSA-2000:043

Affected versions:      7.1

Problem Description:

The exploit that was not fixed with the previous Zope hotfix involves the getRoles method of user objects contained in the default UserFolder implementation returning a mutable Python type. Because the mutable object is still associated with the persistent User object, users with the ability to edit DTML could arrange to give themselves extra roles for the duration of a single request by mutating the roles list as part of the request processing. Further investigation revealed that it was possible to access the mutable attribute directly to perform the same exploit.

Please note that this update supercedes the previous advisory dated August 16th (MDKSA-2000:035).


Please verify these md5 checksums of the updates prior to upgrading to ensure the integrity of the downloaded package. You can do this by running the md5sum program on the downloaded package by using "md5sum package.rpm".
