AI-suggested
A fix is available in OW2 ASM version 9.11 and later. Users should upgrade to version 9.11 or newer to remediate this vulnerability. No other mitigation or workaround is indicated.
Description
OW2 ASM versions before 9.11 have a vulnerability in the asm-commons JSRInlinerAdapter component that causes uncontrolled memory allocation when processing nested JSR/RET subroutines. This can lead to exponential memory consumption, resulting in an OutOfMemoryError that crashes the Java Virtual Machine (JVM). The vulnerability affects specific older versions of ASM and has a medium severity rating.
