The remote CentOS Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the CESA-2024:0647 advisory.

  - A race condition vulnerability was found in rpm. A local unprivileged user could use this flaw to bypass     the checks that were introduced in response to CVE-2017-7500 and CVE-2017-7501, potentially gaining root     privileges. The highest threat from this vulnerability is to data confidentiality and integrity as well as     system availability. (CVE-2021-35937)

  - A symbolic link issue was found in rpm. It occurs when rpm sets the desired permissions and credentials     after installing a file. A local unprivileged user could use this flaw to exchange the original file with     a symbolic link to a security-critical file and escalate their privileges on the system. The highest     threat from this vulnerability is to data confidentiality and integrity as well as system availability.
    (CVE-2021-35938)

  - It was found that the fix for CVE-2017-7500 and CVE-2017-7501 was incomplete: the check was only     implemented for the parent directory of the file to be created. A local unprivileged user who owns another     ancestor directory could potentially use this flaw to gain root privileges. The highest threat from this     vulnerability is to data confidentiality and integrity as well as system availability. (CVE-2021-35939)

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