OW2 ASM 3.0 before 9.11 contains an uncontrolled recursion vulnerability in ClassWriter.replaceAsmInstructions() that allows attackers to cause denial of service through crafted class files. Attackers can supply a class with a large method containing many long forward jumps, triggering unbounded toByteArray() recursion and a StackOverflowError during transformation.
