The remote Ubuntu 16.04 LTS / 18.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-4223-1 advisory.

    Jan Jancar, Petr Svenda, and Vladimir Sedlacek discovered that a side- channel vulnerability existed in     the ECDSA implementation in OpenJDK. An Attacker could use this to expose sensitive information.
    (CVE-2019-2894)

    It was discovered that the Socket implementation in OpenJDK did not properly restrict the creation of     subclasses with a custom Socket implementation. An attacker could use this to specially create a Java     class that could possibly bypass Java sandbox restrictions. (CVE-2019-2945)

    Rob Hamm discovered that the Kerberos implementation in OpenJDK did not properly handle proxy credentials.
    An attacker could possibly use this to impersonate another user. (CVE-2019-2949)

    It was discovered that a NULL pointer dereference existed in the font handling implementation in OpenJDK.
    An attacker could use this to cause a denial of service (application crash). (CVE-2019-2962)

    It was discovered that the Concurrency subsystem in OpenJDK did not properly bound stack consumption when     compiling regular expressions. An attacker could use this to cause a denial of service (application     crash). (CVE-2019-2964)

    It was discovered that the JAXP subsystem in OpenJDK did not properly handle XPath expressions in some     situations. An attacker could use this to cause a denial of service (application crash). (CVE-2019-2973,     CVE-2019-2981)

    It was discovered that the Nashorn JavaScript subcomponent in OpenJDK did not properly handle regular     expressions in some situations. An attacker could use this to cause a denial of service (application     crash). (CVE-2019-2975)

    It was discovered that the String class in OpenJDK contained an out-of- bounds access vulnerability. An     attacker could use this to cause a denial of service (application crash) or possibly expose sensitive     information. This issue only affected OpenJDK 11 in Ubuntu 18.04 LTS, Ubuntu 19.04, and Ubuntu 19.10.
    (CVE-2019-2977)

    It was discovered that the Jar URL handler in OpenJDK did not properly handled nested Jar URLs in some     situations. An attacker could use this to cause a denial of service (application crash). (CVE-2019-2978)

    It was discovered that the Serialization component of OpenJDK did not properly handle deserialization of     certain object attributes. An attacker could use this to cause a denial of service (application crash).
    (CVE-2019-2983)

    It was discovered that the FreetypeFontScaler class in OpenJDK did not properly validate dimensions of     glyph bitmap images read from font files. An attacker could specially craft a font file that could cause a     denial of service (application crash). (CVE-2019-2987)

    It was discovered that a buffer overflow existed in the SunGraphics2D class in OpenJDK. An attacker could     possibly use this to cause a denial of service (excessive memory consumption or application crash).
    (CVE-2019-2988)

    It was discovered that the Networking component in OpenJDK did not properly handle certain responses from     HTTP proxies. An attacker controlling a malicious HTTP proxy could possibly use this to inject content     into a proxied HTTP connection. (CVE-2019-2989)

    It was discovered that the font handling implementation in OpenJDK did not properly validate TrueType font     files in some situations. An attacker could specially craft a font file that could cause a denial of     service (excessive memory consumption). (CVE-2019-2992)

    It was discovered that the JavaDoc generator in OpenJDK did not properly filter out some HTML elements     properly, including documentation comments in Java source code. An attacker could possibly use this to     craft a Cross-Site Scripting attack. (CVE-2019-2999)
