DescriptionOW2 ASM 3.0 before 9.11 contains an uncontrolled recursion vulnerability in SignatureReader.parseType() that allows attackers to exhaust the stack via deeply nested generic type signatures. Attackers can supply a crafted class file with a long Signature attribute containing many nested type arguments to trigger a StackOverflowError during class transformation, causing denial of service.
