During malware research I bumped int problem with my Python based file analyzer: miscreants are modifying ZIP file header parts so, that python based automated analysis tools are unable to process the contents but intended clients are able to open the files with end-user applications and extract the possibly malicious contents. Proposed patch makes it possible to process the ZIP files even if such conditions occur. Default behavior remains the same (raise BadZipFile exception).
