      Description

      As announced on the mailing list:

      http://www.modpython.org/pipermail/mod_python/2006-February/020284.html

      If you are using the recently released mod_python 3.2.7 please beware that a
      security issue was discovered in the FileSession code.

      You are vulnerable only if you are using mod_python 3.2.7 AND you are using
      FileSession to keep sessions. FileSession is new in 3.2.7 and is not enabled by
      default, therefore if you are using mod_python Session in its default
      configuration you are not vulnerable.

      The extent of this vulnerability is limited. Only a user who already has an
      account (or some ability to write to the filesystem) on the system running
      httpd could exploit it, and to the best of our knowledge such a user could
      potentially cause httpd to execute arbitrary code.

      We are working on a security release of the next version of mod_python and
      expect it to be out shortly. Until then, please do not use FileSession.
