Piotr Karwasz updated COMPRESS-711:
-----------------------------------
Assignee: Piotr Karwasz
> Incorrect CPIO checksum verification
> ------------------------------------
>
> Key: COMPRESS-711
> URL: https://issues.apache.org/jira/browse/COMPRESS-711
> Project: Commons Compress
> Issue Type: Bug
> Reporter: Piotr Karwasz
> Assignee: Piotr Karwasz
> Priority: Minor
>
> {{CpioArchiveInputStream}} computes the CRC checksum on the wrong data if
> {{read()}} is invoked with a non-zero offset. This leads to incorrect
> checksum verification and causes archives to fail validation.
> *Steps to Reproduce*:
> * Read a {{crc}} archive (magic {{070702}}) using
> {{CpioArchiveInputStream.read(byte[] b, int off, int len)}} with {{off > 0}}.
> * At the end of the entry an exception will be thrown.
