New Features

  • import_and_analyse_file
  • import_and_analyse_directory
• New TIFF content management policy introduced.
  • now includes an <undefined_type> content switch for the handling of IFD entries.
  • A setting of sanitise, allow, or disallow can be used to handle IFD entries of type undefined and their associated value / offset referenced data.

Fixes and Improvements

• Fixed issue in PDF where Digital Signatures stored inside Acroforms were handled under the Acroform and not the Digital Signature content management policy.
• Fixed issue in XLS where some embedded files were reported with an allowedID of '0'.
• Extended content validation and remediation in TIFF.
• Fixed issue in XLS where some remedy items were missing from the analysis report.
• Fixed issue in XLS where a "Failure occurred while post-processing CFB nodes" issue item was reported instead of "Digital signatures present in Digital Signature Stream".
• Fixed issue in DOCX files (created using the desktop version of Word) where the combination of Aptos and Emoji fonts could cause segmentation faults during engine processing.
• Decoupled file processing failures from the (-16) run session return code (which is used for files rejected by policy). A (-1) return is now returned instead.
• Fixed issue affecting Java wrapper integrations where a '-11 Failed to initialise camera' was returned where attempting to process a second file after an initial problematic file failed engine processing.
• Fixed issue affecting the Windows build where the presence of some Unicode characters in the file path led to a "-6 unableToLoadInput" error being returned.
• Fixed issue in XLS on Document Import that could lead to the failure "Failure [b6] occurred while processing CFB node : '#01CompObj'" where using certain combinations of content management policies.
• Updated Quazip dependency from version 0.7.4 to 1.4
• Updated SafeInt dependency from version 3.0.20 to 3.0.28a
• Updates to config.xml (example policy file) and gwConfigurationManagement.xsd.

Defects and Limitations

• The Alpine library is currently excluded from the release package and will be reintroduced in a future release.
• The JavaScript wrapper is currently excluded from the release package and will be reintroduced in a future release.
• The Word Search Java wrapper compatibility is currently limited to JRE8.
• PDFs generated via the MS Outlook Adobe plugin are not supported.
• Word Search analysis XML no longer reports structural content or changes.
• Processing times may be impacted by changes made to licensing functionality.
• Processing files using multiple threads is not supported. Spawning multiple processes is advised in order to facilitate parallel processing.
• Word Search functionality is provided as Beta:
  • 'text' or 'regex' cannot be the same for 'require' or 'allow'/'disallow' as this will regenerate the file and ignore the 'disallow' or 'require' setting
  • | symbol at the start or end of 'require' can potentially cause the Engine to hang where using regex search policies
