   OW2 ASM 3.0 before 9.11 contains an uncontrolled memory allocation vulnerability in the asm-commons JSRInlinerAdapter that inlines JSR/RET subroutines without memory or work limits. Attackers can supply a crafted class file with nested subroutines to force O(2^n) memory allocation, causing an OutOfMemoryError that crashes the JVM.
