Hotfix_2001-07-25 This is a "hotfix" product. Hotfix products can be installed to incorporate modifications to Zope at runtime without requiring an immediate installation upgrade. Hotfix products are installed just as you would install any other Zope product. This hotfix addresses a potential denial-of-service vulnerability in applications that use the Python cgi module (cgi.py) for parsing of "multipart" Web form data (Zope uses this functionality internally). More detailed information is available in the Python bug tracker at SourceForge: http://sourceforge.net/tracker/?group_id=5470&atid=105470&func=detail&aid=443120 While we are not aware of any instances of abuse of this vulnerability, we *highly* recommend that any Zope site running versions of Zope up to and including 2.4.0 have this hotfix product installed to mitigate this issue. (Zope 2.4.1 will not require the installation of a separate hotfix).
