CVE-2019-2992: Medium severity IBM Cognos Controller 10.4.2 vulnerability
An unspecified vulnerability in Java SE related to the 2D component could allow an unauthenticated attacker to cause a denial of service resulting in a low availability impact using unknown attack vectors.
Other sources
It was discovered that the CMap class in the 2D component in OpenJDK did not check if TrueType font files could contain character map tables of declared size before performing memory allocation. A specially crafted font file could use this flaw to cause a Java application to use an excessive amount of memory and possibly unexpectedly exist due to an out of memory condition.

Vulnerability in the Java SE, Java SE Embedded product of Oracle Java SE (component: 2D). 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 does not apply to Java deployments, typically in servers, that load and run only trusted code (e.g., code installed by an administrator). 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).
