Greetings,

attached diff fixes CVE-2019-12900 (BZ2_decompress in decompress.c in
bzip2 through 1.0.6 has an out-of-bounds write when there are many
selectors.) The vulnerability has a CVSS v3.0 score of 9.8 "CRITICAL".

It is essentially the patch from
https://gitlab.com/federicomenaquintero/bzip2/commit/74de1e2e6ffc9d51ef9824db71a8ffee5962cdbc
