CVE-2020-14562: Medium severity Oracle JDK vulnerability
It was discovered that the TIFF plugin in the ImageIO component of OpenJDK did not restrict the amount of memory allocated when reading TIFF image files. A specially-crafted TIFF file could cause a Java application using ImageIO to allocate an excessive amount of memory disproportionate to the image size.
Other sources
Vulnerability in the Java SE product of Oracle Java SE (component: ImageIO). Supported versions that are affected are Java SE: 11.0.7 and 14.0.1. Easily exploitable vulnerability allows unauthenticated attacker with network access via multiple protocols to compromise Java SE. Successful attacks of this vulnerability can result in unauthorized ability to cause a partial denial of service (partial DOS) of Java SE. Note: This vulnerability applies to Java deployments, typically in clients running sandboxed Java Web Start applications or sandboxed Java applets, that load and run untrusted code (e.g., code that comes from the internet) and rely on the Java sandbox for security.
