The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to application does not properly control consumption of internal resources. When using the Chainsaw or SocketAppender components with Log4j 1.x on JRE less than 1.7, an attacker that manages to cause a logging entry involving a specially-crafted (i.e., deeply nested) hashmap or hashtable (depending on which logging component is in use) to be processed can exhaust the available memory in the virtual machine and achieve denial of service when the object is deserialized.
