* bzip2recover: Fix use after free issue with outFile (CVE-2016-3189)
* Make sure nSelectors is not out of range (CVE-2019-12900)
1.0.8 (13 Jul 19)
~~~~~~~~~~~~~~~~~
* Accept as many selectors as the file format allows.
This relaxes the fix for CVE-2019-12900 from 1.0.7
so that bzip2 allows decompression of bz2 files that
use (too) many selectors again.
* Fix handling of large (> 4GB) files on Windows.
* Cleanup of bzdiff and bzgrep scripts so they don't use
any bash extensions and handle multiple archives correctly.
* There is now a bz2-files testsuite at
https://sourceware.org/git/bzip2-tests.git
