28 Sep '11

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 The Zope security response team is pre-announcing a fix for a vulnerability in Zope 2.12.x and Zope 2.13.x that allows execution of arbitrary code by anonymous users. This is a severe vulnerability that allows an unauthenticated attacker to employ a carefully crafted web request to execute arbitrary commands with the privileges of the Zope service. Versions Affected: Zope 2.12.x and Zope 2.13.x. Versions Not Affected: Zope 2.9.x, Zope 2.10.x, Zope 2.11.x This is a pre-announcement. Due to the severity of this issue we are providing an advance warning of an upcoming patch, which will be released 2011-10-04 15:00 UTC. What you should do in advance of patch availability =================================================== Due to the nature of the vulnerability, the security team has decided to pre-announce that a fix is upcoming before disclosing the details. This is to ensure that concerned users can plan around the release. As the fix being published will make the details of the vulnerability public, we are recommending that all users plan a maintenance window for 30 minutes either side of the announcement where your site is completely inaccessible in which to install the fix. Meanwhile, we STRONGLY recommend that you take the following steps to protect your site: - - Make sure that the Zope service is running with with minimum privileges. Ideally, the Zope and ZEO services should be able to write only to log and data directories. - - Use an intrusion detection system that monitors key system resources for unauthorized changes. - - Monitor your Zope, reverse-proxy request and system logs for unusual activity. In this case, these are standard precautions that should be employed on any production system. Extra help ========== Should you not have in-house server administrators or a service agreement looking after your website you can find consultancy companies on plone.net. There is also free support available online via Zope mailing lists and the #zope IRC channels. Questions and Answers ===================== Q: When will the patch be made available? A: The Security Team will release the patch at 2011-10-04 15:00 UTC. Q. What will be involved in applying the patch? A. Patches are made available as tarball-style archives that may be unpacked into the “products” folder of a buildout installation and as Python packages that may be installed by editing a buildout configuration file and running buildout. Patching is generally easy and quick to accomplish. Q: How was this vulnerability found? A: This issue was found as part of a routine audit performed by the Plone Security team. Q: My site is highly visible and mission-critical. I hear the patch has already been developed. Can I get the fix before the release date? A: No. The patch will be made available to all users at the same time. There are no exceptions. Q: If the patch has been developed already, why isn't it already made available to the public? A: The Security Team is still testing the patch and running various scenarios thoroughly. The team is also making sure everybody has appropriate time to plan to patch their Zope installation(s). Some consultancy organizations have hundreds of sites to patch and need the extra time to coordinate their efforts with their clients. Q: How does one exploit the vulnerability? A: This information will not be made available until after the patch is made available. Q: Is there a CVE record for this vulnerability? A: Not yet. This information will be added when available. If you have specific questions about this vulnerability or its handling, contact the Zope Security Team, security-response(a)zope.org. To report potentially security-related issues, please send a mail to the Zope Security Team at security-response(a)zope.org. The security team is always happy to credit individuals and companies who make responsible disclosures.

MailingLogger 3.5.0 Released!
by Chris Withers 24 Sep '11

24 Sep '11

I'm pleased to announce a new release of Mailinglogger. Mailinglogger provides two handlers for the standard python logging framework that enable log entries to be emailed either as the entries are logged or as a summary at the end of the running process. The handlers have the following features: - customisable and dynamic subject lines for emails sent - emails sent with a configurable headers for easy filtering - flood protection to ensure the number of emails sent is not excessive - support for SMTP servers that require authentication - fully documented and tested The only change for this release was to add an X-Log-Level header to emails sent. For MailingLogger, this is the level of the log message being emailed. For SummarisingLogger this is the highest level of any of the messages handled. Full docs can be found here: http://packages.python.org/mailinglogger/ For more information, please see: http://www.simplistix.co.uk/software/python/mailinglogger or http://pypi.python.org/pypi/mailinglogger cheers, Chris -- Simplistix - Content Management, Zope & Python Consulting - http://www.simplistix.co.uk
