ELSA-2022-7585 advisory.

  - Null source pointer passed as an argument to memcpy() function within TIFFReadDirectory() in tif_dirread.c
    in libtiff versions from 4.0 to 4.3.0 could lead to Denial of Service via crafted TIFF file. For users
    that compile libtiff from sources, a fix is available with commit 561599c. (CVE-2022-0562)

  - Reachable Assertion in tiffcp in libtiff 4.3.0 allows attackers to cause a denial-of-service via a crafted
    tiff file. For users that compile libtiff from sources, the fix is available with commit 5e180045.
    (CVE-2022-0865)

  - A heap buffer overflow in ExtractImageSection function in tiffcrop.c in libtiff library Version 4.3.0
    allows attacker to trigger unsafe or out of bounds memory access via crafted TIFF image file which could
    result into application crash, potential information disclosure or any other context-dependent impact
    (CVE-2022-0891)

  - Null source pointer passed as an argument to memcpy() function within TIFFFetchNormalTag () in
    tif_dirread.c in libtiff versions up to 4.3.0 could lead to Denial of Service via crafted TIFF file.
    (CVE-2022-0908)

  - Null source pointer passed as an argument to memcpy() function within TIFFFetchStripThing() in
    tif_dirread.c in libtiff versions from 3.9.0 to 4.3.0 could lead to Denial of Service via crafted TIFF
    file. For users that compile libtiff from sources, the fix is available with commit eecb0712.
    (CVE-2022-0561)

  - LibTIFF 4.3.0 has an out-of-bounds read in _TIFFmemcpy in tif_unix.c in certain situations involving a
    custom tag and 0x0200 as the second word of the DE field. (CVE-2022-22844)

  - Out-of-bounds Read error in tiffcp in libtiff 4.3.0 allows attackers to cause a denial-of-service via a
    crafted tiff file. For users that compile libtiff from sources, the fix is available with commit 408976c4.
    (CVE-2022-0924)

  - Divide By Zero error in tiffcrop in libtiff 4.3.0 allows attackers to cause a denial-of-service via a
    crafted tiff file. For users that compile libtiff from sources, the fix is available with commit f8d0f9aa.
    (CVE-2022-0909)

  - A stack buffer overflow flaw was found in Libtiffs' tiffcp.c in main() function. This flaw allows an
    attacker to pass a crafted TIFF file to the tiffcp tool, triggering a stack buffer overflow issue,
    possibly corrupting the memory, and causing a crash that leads to a denial of service. (CVE-2022-1355)
