CVE-2018-2603

First published: Mon Jan 15 2018(Updated: )

It was discovered that the DerValue class in the Libraries component of OpenJDK failed to sufficiently limit the amount of memory allocated when reading DER (Distinguished Encoding Rules) encoded input. It could allocate a large amount of memory even when processing short input. A remote attacker could possibly use this flaw to make a Java application use an excessive amount of memory if it parsed attacker-supplied DER encoded input.
