From Red Hat Security Advisory 2020:2970 :

The remote Redhat Enterprise Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2020:2970 advisory.

  • OpenJDK: Incorrect handling of access control context in ForkJoinPool (Libraries, 8237117) (CVE-2020-14556)

  • OpenJDK: Excessive memory usage in ImageIO TIFF plugin (ImageIO, 8233239) (CVE-2020-14562)

  • OpenJDK: Incomplete interface type checks in Graal compiler (Hotspot, 8236867) (CVE-2020-14573)

  • OpenJDK: HostnameChecker does not ensure X.509 certificate names are in normalized form (JSSE, 8237592) (CVE-2020-14577)

  • OpenJDK: Bypass of boundary checks in nio.Buffer via concurrent access (Libraries, 8238920) (CVE-2020-14583)

  • OpenJDK: Incomplete bounds checks in Affine Transformations (2D, 8240119) (CVE-2020-14593)

  • OpenJDK: XML validation manipulation due to incomplete application of the use-grammar-pool-only feature (JAXP, 8242136) (CVE-2020-14621)

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