> Parsing PAX headers fails with NegativeArraySizeException
> ---------------------------------------------------------
>
> Key: COMPRESS-355
> URL: https://issues.apache.org/jira/browse/COMPRESS-355
> Project: Commons Compress
> Issue Type: Bug
> Components: Archivers
> Affects Versions: 1.11
> Reporter: Jeremy Gustie
> Fix For: 1.12
>
>
> The {{TarArchiveInputStream.parsePaxHeaders}} method fails with a
> {{NegativeArraySizeException}} when there is an empty line at the end of the
> headers.
> The inner loop starts reading the length, but it gets a newline (10) and ends
> up subtracting '0' (48) from it; the result is a negative length that blows
> up an attempt to allocate the {{rest}} array.
> I would say that a check to see if {{ch}} is less the '0' and break the loop
> if it is.
> I used {{npm pack [email protected]}} to generate a tarball with this issue.
