Fedora 30: FEDORA-2019-71b2273a9f Critical Libarchive RAR Reader Fix

Libarchive is a programming library that can create and read several different

streaming archive formats, including most popular tar variants, several cpio

formats, and both BSD and GNU ar variants. It can also write shar archives and

read ISO9660 CDROM images and ZIP archives.

Security fix for CVE-2019-18408 RAR reader: fix use after free If

read_data_compressed() returns ARCHIVE_FAILED, the caller is allowed to continue

with next archive headers. We need to set rar->start_new_table after the

ppmd7_context got freed, otherwise it won't be allocated again.
