The remote Redhat Enterprise Linux 8 host has one or more packages installed that are affected by multiple vulnerabilities that have been acknowledged by the vendor but will not be patched.
libtiff: Heap-based buffer overflow in TIFF2PDF tool (CVE-2020-35524)
libtiff: heap-buffer overflow via extractContigSamplesBytes() at /libtiff/tools/tiffcrop.c (CVE-2023-25434)
tools/pal2rgb.c in pal2rgb in LibTIFF 4.0.9 allows remote attackers to cause a denial of service (TIFFSetupStrips heap-based buffer overflow and application crash) or possibly have unspecified other impact via a crafted TIFF file. (CVE-2017-17095)
Note that Nessus has not tested for these issues but has instead relied on the package manager’s report that the package is installed.
