The remote Rocky Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the RLSA-2024:5079 advisory.
* libtiff: Heap-based buffer overflow in ChopUpSingleUncompressedStrip in tif_dirread.c (CVE-2018-15209)
* libtiff: Buffer Overflow via /libtiff/tools/tiffcrop.c (CVE-2023-25433)
* libtiff: heap-based buffer overflow in cpStripToTile() in tools/tiffcp.c (CVE-2023-6228)
* libtiff: Segment fault in libtiff in TIFFReadRGBATileExt() leading to denial of service (CVE-2023-52356)
Tenable has extracted the preceding description block directly from the Rocky Linux security advisory.
Note that Nessus has not tested for these issues but has instead relied only on the application’s self-reported version number.
