Jukka Zitting updated COMPRESS-191:
-----------------------------------
Attachment: 0001-COMPRESS-191-Too-relaxed-tar-detection-in-ArchiveStr.patch
The attached patch adds heuristics for verifying the tar header checksum, and
uses that mechanism to better avoid false positives in ArchiveStreamFactory.
> Too relaxed tar detection in ArchiveStreamFactory

> Key: COMPRESS-191
> URL: https://issues.apache.org/jira/browse/COMPRESS-191
> Project: Commons Compress
> Issue Type: Improvement
> Components: Archivers
> Affects Versions: 1.2, 1.3, 1.4, 1.4.1
> Reporter: Jukka Zitting
> Priority: Minor
> Labels: tar

>
>
> The relaxed tar detection logic added in COMPRESS-177 unfortunately matches
> also some non-tar files like a [test AIFF
> file|https://svn.apache.org/repos/asf/tika/trunk/tika-parsers/src/test/resources/test-documents/testAIFF.aif]
> that Apache Tika uses. It would be good to improve the detection heuristics
> to still match files like the one in COMPRESS-177 but avoid false positives
> like the AIFF file in Tika.
