                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".
