Subject [jira] [Commented] (COMPRESS-444) Version to extract incorrect in Local File Header
Date Tue, 20 Feb 2018 05:18:00 GMT

    [ https://issues.apache.org/jira/browse/COMPRESS-444?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16369727#comment-16369727

Stefan Bodewig commented on COMPRESS-444:
-----------------------------------------

Actually I just had a second look at our changelog. The fix is in 1.15 (and later versions,
of course). The latest version is 1.16.1 which only fixes the OSGi manifest when compared
to 1.16.

> A friend is generating ZIP files with Maven Assembly Plugin, which uses Plexus Archiver,
which uses Commons Compress. One of his files tripped a validation check in SharpZipLib, see [https://github.com/KSP-CKAN/CKAN/issues/2285].
> Here's a link to the ZIP:
> [https://github.com/rleroy/CivilianPopulation/releases/download/2.0.12/ksp-civilian-population-mod-2.0.12.zip]
> The LFH in question starts:
> {{00000400 74 69 6c 69 74 79 2f 50 4b 03 04 *0a 00* 08 08 *08* |tility/PK.......|}}
> Note the *highlighted* bytes. The *0a 00* means that the version to extract is PKZip
1.0. The *08* means that the compression method is DEFLATED. These values are not compatible;
by Commons Compress's own code logic, DEFLATED should require version 2.0, which would appear
in the LFH as *14 00*. Notably, the CFH for this same file _does_ have version 2.0:
> {{00e0e5f0 73 2f 55 74 69 6c 69 74 79 2f 50 4b 01 02 14 03 |s/Utility/PK....|}}
>  {{00e0e600 *14* *00* 08 08 08 00 ab b8 30 4c 43 fa a3 ea 50 00 |........0LC...P.|}}
> {{         ^^ ^^}}
> I have not yet been able to identify the cause of this issue.
