JSON

The mtree bidder in libarchive 3.2.1 does not keep track of line sizes when
extending the read-ahead, which allows remote attackers to cause a denial
of service (crash) via a crafted file, which triggers an invalid read in
the (1) detect_form or (2) bid_entry function in
libarchive/archive_read_support_format_mtree.c.
