The remote CentOS Linux 8 host has packages installed that are affected by a vulnerability as referenced in the CESA-2021:1301 advisory.

  • OpenJDK: Incomplete enforcement of JAR signing disabled algorithms (Libraries, 8249906) (CVE-2021-2163)

Note that Nessus has not tested for this issue but has instead relied only on the application’s self-reported version number.
