libarchive version commit 9693801580c0cf7c70e862d305270a16b52826a7 onwards (release v3.2.0 onwards) contains a CWE-20: Improper Input Validation vulnerability in WARC parser - libarchive/archive_read_support_format_warc.c, _warc_read() that can result in DoS - quasi-infinite run time and disk usage from tiny file. This attack appear to be exploitable via the victim must open a specially crafted WARC file.
Stack-based buffer overflow in the safe_fprintf function in tar/util.c in libarchive 3.2.1 allows remote attackers to cause a denial of service via a crafted non-printable multibyte character in a filename.
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.
The read_Header function in archive_read_support_format_7zip.c in libarchive 3.2.1 allows remote attackers to cause a denial of service (out-of-bounds read) via multiple EmptyStream attributes in a header in a 7zip archive.
