The remote Redhat Enterprise Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2019:1817 advisory.
OpenJDK: Side-channel attack risks in Elliptic Curve (EC) cryptography (Security, 8208698) (CVE-2019-2745)
OpenJDK: Insufficient checks of suppressed exceptions in deserialization (Utilities, 8212328) (CVE-2019-2762)
OpenJDK: Unbounded memory allocation during deserialization in Collections (Utilities, 8213432) (CVE-2019-2769)
OpenJDK: Insufficient restriction of privileges in AccessController (Security, 8216381) (CVE-2019-2786)
OpenJDK: Missing URL format validation (Networking, 8221518) (CVE-2019-2816)
OpenJDK: Non-constant time comparison in ChaCha20Cipher (Security, 8221344) (CVE-2019-2818)
OpenJDK: Incorrect handling of certificate status messages during TLS handshake (JSSE, 8222678) (CVE-2019-2821)
Note that Nessus has not tested for these issues but has instead relied only on the application’s self-reported version number.
