Security Options

Compressed files and archives can be exploited by attackers using carefully crafted files which can cause issues on expansion, either by generating extremely large files from a small compressed file, or by generating large numbers of files from an innocuously small looking file. The following settings. See the Wikipedia article ' Zip Bomb ' for further details. The default settings here should be suitable to extract most files whilst limiting attack vectors

Maximum expanded size (bytes)

The maximum allowed size in bytes of the decompressed file(s) from the input binary object. A negative value indicates no limit

Maximum Compression ratio

The maximum allowed compression ratio. A negative value indicates no limit

Maximum number of expanded files

The maximum allowed number of files a multi-file concatenated compressed binary object will expand to. A negative value indicates no limit. Option only available to compression formats supporting concatenation

Fail on explosive expansion

Should the node fail if explosive decompression is detected by any of the settings supplied? If not, then a warning will be set and at least one row for each input row will be present in the table. In the event that the first output row triggered the warning, then missing values will be added to the output row
