The remote Rocky Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the RLSA-2020:4820 advisory.
An issue was discovered in GNOME file-roller before 3.29.91. It allows a single ./…/ path traversal via a filename contained in a TAR archive, possibly overwriting a file during extraction. (CVE-2019-16680)
fr-archive-libarchive.c in GNOME file-roller through 3.36.1 allows Directory Traversal during extraction because it lacks a check of whether a file’s parent is a symlink to a directory outside of the intended extraction location. (CVE-2020-11736)
Note that Nessus has not tested for these issues but has instead relied only on the application’s self-reported version number.
