OW2 ASM 9.11 before 9.11.1 Denial of Service via Infinite Loop in Label.resolve()
Description

OW2 ASM 9.11 before 9.11.1 contains an infinite loop vulnerability in Label.resolve() caused by 16-bit forward-reference offsets truncating when rewritten methods exceed 64 KB. Attackers can supply crafted class files whose transformed code grows past 65535 bytes, hanging ClassReader.accept() and denying service to build tools, instrumenters, agents, or analyzers.
