Security alert: use of Through-the-Web reStructuredText
by Jim Fulton 08 Jul '06

08 Jul '06

Recently, a serious security flaw was found in Zope 2 due to it's improper support for allowing reStructuredText to be edited through- the-web. reStructuredText has directives that allow inclusion of any file a Zope process could read and inclusion of data obtained from fetching arbitrary URLs. In a trusted environment, these directives have legitimate uses. The feature of including files and URL results should not be enabled for text entered from untrusted sources, which applies to most through-the-web interactions. The recent hotfix: http://www.zope.org/Products/Zope/Hotfix-2006-07-05/Hotfix-2006-07-05 addresses the problem for Zope 2. It is safe to allow reStructuredText through the web with care. The inclusion of files or URL results can be disabled, but the programmer must explicitly disable the feature. It is not disabled by default. It is also critical that a developer who exposes through-the-web reStructuredText have tests to verify that the file/url inclusion feature has been disabled. Zope 3 itself, as released, doesn't have this problem because it doesn't allow reST entry through the web. There are third-party applications, however, including 2 packages in the Zope 3 subversion tree that do have this problem. I strongly urge you to avoid using any Zope package that allows through-the-web input of reStructuredText unless you can verify that file/url has been properly disabled. The zwiki and bugtracker packages do not currently disable file/url inclusion and should not be used in situations in which users who are not highly trusted have access to these applications. If you are using a Zope 3 checkout, these packages are currently included and enabled. I plan to remove these packages from the Zope 3 repository tree within the next few hours. If you are using a checkout-based Zope 3 installation that exposes these packages to untrusted users, you are strongly urged to disable these packages by removing the following files from your package-includes directory: zwiki-configure.zcml bugtracker-configure.zcml Removing these files will also avoid problems when you update your checkout later, as these will refer to non-existent packages.

Serious security problem with Zope 2
by Jim Fulton 05 Jul '06

05 Jul '06

We have recently discovered that there are (still) very serious security problems with the integration of reStructured Text (docutils) into Zope 2. We have prepared a hot fix for this problem: http://www.zope.org/Products/Zope/Hotfix-2006-07-05/Hotfix-20060705/ See: http://www.zope.org/Products/Zope/Hotfix-2006-07-05/Hotfix-20060705/ README.txt for installation instructions. It is important to install this hotfix as soon as possible. This fix will disable the reStructuredText 'raw' directive. Much thanks goes to Tres Seaver for analyzing the problem and developing the hotfix! Jim -- Jim Fulton mailto:jim@zope.com Python Powered!

linktally 0.1.0: Keep track of your most popular CMS content
by Martijn Pieters 04 Jul '06

04 Jul '06

Pareto is happy to announce the first preview release of linktally, version 0.1.0: http://plone.org/products/linktally What is linktally ----------------- Zope, and most CMS-es in fact, is not optimized to write on every page access. This makes page counters impractical. Add a squid cache and most visits won't even be seen by your CMS. Instead, linktally utilizes your Squid, Apache or Zope log file to periodically tally content accesses, storing these in a sqlite3 database. A separate, CMS-specific tool then provides rankings (by type if need be) for the past week, month and year. This initial release includes a CMF tool to provide rankings by past week, month, or year, for all tracked content or for specific types only. We've deployed this tool in a few Plone sites already. Note that this is an initial preview alpha release, and is still missing some features. In the future it should support more than just Apache Combined format, for example. Plugins for other CMS-es like Silva, CPS or even non-python systems are also on the TODO list. Martijn Pieters

28 Jun '06

What's New? =========== The deadline for early-bird registration for the Vancouver Python Workshop is this Friday, June 30th. Early-bird registration is significantly discounted over normal registration, so register now at: http://www.vanpyz.org/conference/registration.html About the Vancouver Python Workshop =================================== The conference will begin with keynote addresses on August 4st by Guido van Rossum [1] and Jim Hugunin [2]. Further talks (and tutorials for beginners) will take place on August 5th and 6th. Ian Cavén [3] will give the closing address. The Vancouver Python Workshop is a community organized and designed for both the beginner and for the experienced Python programmer with: * tutorials for beginning programmers * advanced lectures for Python experts * case studies of Python in action * after-hours social events * informative keynote speakers More information see: http://www.vanpyz.org/conference/ or contact Brian Quinlan at: brian(a)sweetapp.com Vancouver ========= In addition to the opportunity to learn and socialize with fellow Pythonistas, the Vancouver Python Workshop also gives visitors the opportunity to visit one of the most extraordinary cities in the world [4]. For more information about traveling to Vancouver, see: http://www.vanpyz.org/conference/vancouver.html http://www.tourismvancouver.com http://en.wikipedia.org/wiki/Vancouver Important dates =============== Early registration (discounted): May 22nd to June 30th Normal registration: from July 1st Keynotes: August 4th Conference and tutorial dates: August 5th and 6th [1] Guido van Rossum (Google) is the inventor of Python and has managed its growth and development for more than a decade. Guido was awarded the Free Software Foundation Award in 2002 and Dr.Dobb's 1999 Excellence in Programming Award. Guido works at Google and spends half of his time on Python. [2] Jim Hugunin (Microsoft) is the creator of numerous innovations that take Python into new application domains. Jim's most recent project, IronPython integrates Python into Microsoft's .NET runtime. Jim's previous project, Jython is Python for the Java runtime and was the second production-quality implementation of Python. Before that, Jim's Numeric Python adapted Python to the needs of number crunching applications. Jim works at Microsoft adapting the .NET runtime to the needs of dynamic languages like Python. [3] Ian Cavén is the primary developer of the Lowry Digital Images motion picture restoration system. This Python and Zope-based system has been used to restore over 150 motion pictures. Highlights include Citizen Kane, Sunset Boulevard and both the Indiana Jones and Star Wars trilogies. While Ian was Chief Scientist at Lowry Digital, his rack of computers grew from a few Macintoshes on his desktop to over six hundred Macintosh and Linux servers - at one point earning Lowry the title as the second biggest installation of parallel processing Maintoshes in the world. In 2005, Lowry Digital Images was acquired by DTS (the famous movie audio company) and renamed DTS Digital Images. The motion picture restoration system has been discussed in publications as diverse as IEEE Spectrum, USA Today, the BBC NEWS, the New York Times and Apple.com. Ian has been a Python enthusiast since 1999. [4] http://news.bbc.co.uk/2/hi/business/2299119.stm http://edition.cnn.com/2006/BUSINESS/06/15/btn.cities/index.html Cheers, Brian
