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 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.
