CVE-2017-3253: High severity Oracle JDK vulnerability
It was discovered that the PNGImageReader in the javax.imageio package of the 2D component of OpenJDK performed parsing of iTXt and zTXt PNG image chunks even when ignoreMetadata was set to true. An attacker able to make a Java application parse a specially crafted PNG image could cause the application to consume an excessive amount of memory.
