From Red Hat Security Advisory 2020:1509 :

The remote Redhat Enterprise Linux 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2020:1509 advisory.

  • OpenJDK: Misplaced regular expression syntax error check in RegExpScanner (Scripting, 8223898) (CVE-2020-2754)

  • OpenJDK: Incorrect handling of empty string nodes in regular expression Parser (Scripting, 8223904) (CVE-2020-2755)

  • OpenJDK: Incorrect handling of references to uninitialized class descriptors during deserialization (Serialization, 8224541) (CVE-2020-2756)

  • OpenJDK: Uncaught InstantiationError exception in ObjectStreamClass (Serialization, 8224549) (CVE-2020-2757)

  • OpenJDK: Incorrect handling of Certificate messages during TLS handshake (JSSE, 8232581) (CVE-2020-2767)

  • OpenJDK: Unexpected exceptions raised by DOMKeyInfoFactory and DOMXMLSignatureFactory (Security, 8231415) (CVE-2020-2773)

  • OpenJDK: Incomplete enforcement of algorithm restrictions for TLS (JSSE, 8232424) (CVE-2020-2778)

  • OpenJDK: Re-use of single TLS session for new connections (JSSE, 8234408) (CVE-2020-2781)

  • OpenJDK: CRLF injection into HTTP headers in HttpServer (Lightweight HTTP Server, 8234825) (CVE-2020-2800)

  • OpenJDK: Incorrect bounds checks in NIO Buffers (Libraries, 8234841) (CVE-2020-2803)

  • OpenJDK: Incorrect type checks in MethodType.readObject() (Libraries, 8235274) (CVE-2020-2805)

  • OpenJDK: Regular expression DoS in Scanner (Concurrency, 8236201) (CVE-2020-2830)

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