log4j:log4j is vulnerable to Denial of Service (DoS) attacks. The vulnerability is due to the Chainsaw or SocketAppender components processing a logging entry with either a deeply nested hashmap or hashtable, which can lead to memory exhaustion when the object is deserialized. An attacker can submit a crafted logging entry and cause Denial of Service if the JRE is below 1.7.
