Linux-Mandrake Security Update Advisory
Package name: Zope
Date: September 1st, 2000
Advisory ID: MDKSA-2000:043
Affected versions: 7.1
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".
To upgrade automatically, use « MandrakeUpdate
If you want to upgrade manually, download the updated package
from one of our FTP server mirrors and uprade with "rpm -Uvh
You can download the updates directly from:

Updated packages are available in the "updates/[ver]/RPMS/"
directory. For example, if you are looking for an updated RPM
package for Linux-Mandrake 7.1, look for it in "updates/7.1/RPMS/".
Updated source RPMs are available as well, but you generally do not
need to download them.
Please be aware that sometimes it takes the mirrors a few hours
to update, so if you want an immediate upgrade, please use one of
the two above-listed mirrors.
