  - In GNU Libextractor 1.4, there is a Divide-By-Zero in EXTRACTOR_wav_extract_method in wav_extractor.c via
    a zero sample rate. (CVE-2017-15266)

  - In GNU Libextractor 1.4, there is a NULL Pointer Dereference in flac_metadata in flac_extractor.c.
    (CVE-2017-15267)

  - In GNU Libextractor 1.4, there is a NULL Pointer Dereference in the EXTRACTOR_nsf_extract_method function
    of plugins/nsf_extractor.c. (CVE-2017-15600)

  - In GNU Libextractor 1.4, there is a heap-based buffer overflow in the EXTRACTOR_png_extract_method
    function in plugins/png_extractor.c, related to processiTXt and stndup. (CVE-2017-15601)

  - In GNU Libextractor 1.4, there is an integer signedness error for the chunk size in the
    EXTRACTOR_nsfe_extract_method function in plugins/nsfe_extractor.c, leading to an infinite loop for a
    crafted size. (CVE-2017-15602)

  - In GNU Libextractor 1.4, there is an out-of-bounds read in the EXTRACTOR_dvi_extract_method function in
    plugins/dvi_extractor.c. (CVE-2017-15922)

  - GNU Libextractor 1.6 allows remote attackers to cause a denial of service (NULL pointer dereference and
    application crash) via a crafted GIF, IT (Impulse Tracker), NSFE, S3M (Scream Tracker 3), SID, or XM
    (eXtended Module) file, as demonstrated by the EXTRACTOR_xm_extract_method function in
    plugins/xm_extractor.c. (CVE-2017-17440)

  - GNU Libextractor before 1.7 has a stack-based buffer overflow in ec_read_file_func (unzip.c).
    (CVE-2018-14346)

  - GNU Libextractor before 1.7 contains an infinite loop vulnerability in EXTRACTOR_mpeg_extract_method
    (mpeg_extractor.c). (CVE-2018-14347)

  - GNU Libextractor through 1.7 has an out-of-bounds read vulnerability in EXTRACTOR_zip_extract_method() in
    zip_extractor.c. (CVE-2018-16430)

  - GNU Libextractor through 1.8 has an out-of-bounds read vulnerability in the function history_extract() in
    plugins/ole2_extractor.c, related to EXTRACTOR_common_convert_to_utf8 in common/convert.c.
    (CVE-2018-20430)

  - GNU Libextractor through 1.8 has a NULL Pointer Dereference vulnerability in the function
    process_metadata() in plugins/ole2_extractor.c. (CVE-2018-20431)
