"The remote Rocky Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the
RLSA-2022:7585 advisory.

  - 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 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)

  - 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)

  - 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)
