The remote AlmaLinux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the ALSA-2023:5353 advisory.
LibTIFF 4.4.0 has an out-of-bounds write in tiffcrop in tools/tiffcrop.c:3502, 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 33aee127. (CVE-2023-0800)
LibTIFF 4.4.0 has an out-of-bounds write in tiffcrop in libtiff/tif_unix.c:368, invoked by tools/tiffcrop.c:2903 and tools/tiffcrop.c:6778, 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 33aee127.
