CVE-2019-2978: Vulnerability in the Java SE, Java SE Embedded product of Oracle Java SE (component: Networking).

Vulnerability in the Java SE, Java SE Embedded product of Oracle Java SE (component: Networking). Supported versions that are affected are Java SE: 7u231, 8u221, 11.0.4 and 13; Java SE Embedded: 8u221. Difficult to exploit vulnerability allows unauthenticated attacker with network access via multiple protocols to compromise Java SE, Java SE Embedded. Successful attacks of this vulnerability can result in unauthorized ability to cause a partial denial of service (partial DOS) of Java SE, Java SE Embedded. Note: This vulnerability applies to Java deployments, typically in clients running sandboxed Java Web Start applications or sandboxed Java applets (in Java SE 8), that load and run untrusted code (e.g., code that comes from the internet) and rely on the Java sandbox for security. This vulnerability can also be exploited by using APIs in the specified Component, e.g., through a web service which supplies data to the APIs. CVSS 3.0 Base Score 3.7 (Availability impacts). CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:L).

Security readout for executives and security teams

CVE-2019-2978 is an Oracle Java networking vulnerability that can let an unauthenticated network attacker cause a limited denial of service. The impact is availability only, not data theft or code execution, and Oracle rated exploitation as difficult with CVSS 3.7. Exposure is most likely where affected Java runtimes remain in use on clients running untrusted sandboxed Java content, or on services passing network-supplied data into Java networking APIs. Treat this as routine patching unless the business still depends on exposed legacy Java runtimes or untrusted Java client content. It is low severity but should not remain indefinitely unpatched. Mitigation focus: Apply Oracle or OS vendor Java/OpenJDK security updates for the affected runtime line.; Check Oracle, Red Hat, Debian, Ubuntu, SUSE, or NetApp guidance for exact fixed packages.; Retire or restrict Java Web Start and applet use with untrusted code where feasible..
