"It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2022-2022-183 advisory.

  - Out-of-bounds Read 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 46dc8fcd.
    (CVE-2022-1056)

  - A heap buffer overflow flaw was found in Libtiffs' tiffinfo.c in TIFFReadRawDataStriped() function. This
    flaw allows an attacker to pass a crafted TIFF file to the tiffinfo tool, triggering a heap buffer
    overflow issue and causing a crash that leads to a denial of service. (CVE-2022-1354)

  - 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)

  - LibTIFF master branch has an out-of-bounds read in LZWDecode in libtiff/tif_lzw.c:619, allowing 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 b4e79bfa. (CVE-2022-1622)

  - LibTIFF master branch has an out-of-bounds read in LZWDecode in libtiff/tif_lzw.c:624, allowing 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 b4e79bfa. (CVE-2022-1623)

  - libtiff's tiffcrop tool has a uint32_t underflow which leads to out of bounds read and write in the
    extractContigSamples8bits routine. An attacker who supplies a crafted file to tiffcrop could trigger this
    flaw, most likely by tricking a user into opening the crafted file with tiffcrop. Triggering this flaw
    could cause a crash or potentially further exploitation. (CVE-2022-2869)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version
