It was discovered that the JNDI component in OpenJDK did not handle DNS resolution errors correctly. An attacker able to trigger such DNS errors could cause a Java application using JNDI to consume memory and CPU time, and possibly block further DNS resolution.

Description Tomas Hoger 2015-07-13 08:40:02 UTC 
It was discovered that the DnsClient client class in the JNDI (Java Naming and Directory Interface) component in OpenJDK failed to properly remove information about an outgoing DNS request from the list of outstanding DNS requests when certain errors occurred during DNS resolution.  An attacker able to trigger such DNS errors could cause a Java application using JNDI to consume memory and possibly block further DNS resolution (after exhausting all DNS transaction ids).
Comment 1 Tomas Hoger 2015-07-14 20:45:57 UTC 
Public now via Oracle Critical Patch Update - July 2015.  Fixed in Oracle Java SE 6u101, 7u85, and 8u51.
