NVD Description

Note: Versions mentioned in the description apply only to the upstream asm package and not the asm package as distributed by Debian. See How to fix? for Debian:unstable relevant fixed versions and status.

OW2 ASM 3.0 before 9.11 contains a denial of service vulnerability that allows attackers to exhaust CPU by supplying crafted class files processed with ClassWriter.COMPUTE_FRAMES. Attackers can craft methods that make the unbounded MethodWriter.computeAllFrames() fix point algorithm converge slowly, tying up transforming threads for unbounded time.
