    416694915449219d505531b1096384f3237dd6cc onwards
    (release v3.1.0 onwards) contains a CWE-415: Double Free
    vulnerability in RAR decoder -
    libarchive/archive_read_support_format_rar.c,
    parse_codes(), realloc(rar->lzss.window, new_size) with
    new_size = 0 that can result in Crash/DoS. This attack
    appear to be exploitable via the victim must open a
    specially crafted RAR archive. (CVE-2018-1000877)

  - libarchive version commit
    416694915449219d505531b1096384f3237dd6cc onwards
    (release v3.1.0 onwards) contains a CWE-416: Use After
    Free vulnerability in RAR decoder -
    libarchive/archive_read_support_format_rar.c that can
    result in Crash/DoS - it is unknown if RCE is possible.
    This attack appear to be exploitable via the victim must
    open a specially crafted RAR archive. (CVE-2018-1000878)

    (release v3.0.2 onwards) contains a CWE-125: Out-of-
    bounds Read vulnerability in 7zip decompression,
    archive_read_support_format_7zip.c, header_bytes() that
    can result in a crash (denial of service). This attack
    appears to be exploitable via the victim opening a
    specially crafted 7zip file. (CVE-2019-1000019)

  - libarchive 3.3.2 suffers from an out-of-bounds read
    within lha_read_data_none() in
    archive_read_support_format_lha.c when extracting a
    specially crafted lha archive, related to lha_crc16.
    (CVE-2017-14503)

  - libarchive version commit
    5a98dcf8a86364b3c2c469c85b93647dfb139961 onwards
    (version v2.8.0 onwards) contains a CWE-835: Loop with
    Unreachable Exit Condition ('Infinite Loop')
    vulnerability in ISO9660 parser,
    archive_read_support_format_iso9660.c,
    read_CE()/parse_rockridge() that can result in DoS by
    infinite loop. This attack appears to be exploitable via
    the victim opening a specially crafted ISO9660 file.
