From security@LINUX-MANDRAKE.COM Fri Sep 1 12:50:21 2000 From: Linux Mandrake Security Team To: BUGTRAQ@SECURITYFOCUS.COM Date: Fri, 1 Sep 2000 00:11:58 -0600 Subject: [BUGTRAQ] MDKSA-2000:043 - Zope update [The following text is in the "iso-8859-1" character set] [Your display is set for the "US-ASCII" character set] [Some characters may be displayed incorrectly] -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 ________________________________________________________________________ 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".
