Jukka Zitting reopened TIKA-216:
--------------------------------
Reopening as the zip file in the Aperture issue is still causing problems for
Tika.
> Zip bomb prevention
> -------------------
>
> Key: TIKA-216
> URL: https://issues.apache.org/jira/browse/TIKA-216
> Project: Tika
> Issue Type: New Feature
> Components: parser
> Reporter: Jukka Zitting
> Assignee: Jukka Zitting
> Fix For: 0.4
>
>
> It would be good to have a mechanism that automatically detects a "zip bomb",
> i.e. a compressed document that expands to excessive amounts of extracted
> text. The classic example is the 42.zip file that's just 42kB in size, but
> expands to about 4 *petabytes* when all layers are fully uncompressed.
> A simple preventive measure could be a Parser decorator that counts the
> number of input bytes and the output characters, and fails with a
> TikaException when the ratio exceeds some configurable limit.
> As another preventive measure, the decorator could also keep track of the
> time (and perhaps even memory, if possible) it takes to process the input
> document. A TikaException would be thrown if processing time exceeds some
> configurable limit.
