Update:

libarchive issues go in the opposite order as issues and as CVEs…

CVE-2017-14503 is libarchive/libarchive#948 and CVE-2017-14501 is libarchive/libarchive#949

Both are found with AFL, both originally reported to Debian, apparently neither Debian nor the upstream has any patches or specific ideas about causes.


(https://nvd.nist.gov/vuln/detail/CVE-2017-14501):

An out-of-bounds read flaw exists in parse_file_info in archive_read_support_format_iso9660.c in libarchive 3.3.2 when extracting a specially crafted iso9660 iso file, related to archive_read_format_iso9660_read_header.
