Official description

OW2 ASM 3.1 before 9.11 contains an excessive memory allocation vulnerability in the asm-commons AdviceAdapter that allows attackers to exhaust memory by supplying crafted class files. Attackers can craft bytecode with many forward jump targets in constructors, causing unbounded stack copies in forwardJumpStackFrames and allocation of hundreds of megabytes, leading to denial of service.
