Denial of Service in Cryptacular
CiphertextHeader.java in Cryptacular before 1.2.4, as used in Apereo CAS and other products, allows attackers to trigger excessive memory allocation during a decode operation, because the nonce array length associated with "new byte" may depend on untrusted input within the header of encoded data.
