In the MIME settings dialog it is possible to set the parameters affecting MIME detection engine. Besides the blacklist / whitelist functionality for selected MIME types, the engine also performs refinement of MIME types for all uploaded files (the original MIME type set by a browser may not be reliable). So if maximum accuracy of file MIME types is desired, this engine should be enabled, even if no blocking is set.
Since version 2.4 the engine can also limit the maximum depth of embedded content and maximum number of embedded objects (e.g. in archives and other compatible containers).
The following parameters can be set:
...
If this is enabled and the check is skipped because the file is too big, the file is considered “clean” (like if the check was performed and found no problems). If this is disabled, then such file is considered “unclean” (like if the check was performed and found a problem) and the whole package will be quarantined.
Maximum embedded content depth (e.g. for archives and documents)
Maximum embedded content depth. When exceeded, the check will be interrupted and file will be quarantined.
Limit maximum number of embedded objects
If enabled, the inspected file is quarantined if the number of embedded objects exceeds the configured threshold.
Maximum number of embedded objects
If the inspected file contains more than the configured number [0-1000000] of embedded objects, it is quarantined.
Maximum number of stored records of detected objects
