The remote Oracle Linux 8 host has packages installed that are affected by a vulnerability as referenced in the ELSA-2022-1546 advisory.
[0.115-13.0.1.el8_5.2]
- Increase timeout to avoid defunct processes [Orabug: 26930744]
[0.115-13.el8_5.2]
- necessary version bump due to build versioning
- Resolves: CVE-2021-4115
Tenable has extracted the preceding description block directly from the Oracle Linux security advisory.
Note that Nessus has not tested for this issue but has instead relied only on the application’s self-reported version number.
