Chain of evidence and sources
OW2 ASM 3.0 ile 9.11 arasındaki sürümler, MethodWriter bileşeninde kuadratik bellek tahsisi açığı barındırır.
Örtüşen istisna işleyicilerine sahip özel sınıf dosyaları, aşırı bellek tüketimine ve JVM çökmelerine sebep olur.
Show the technical text from the sources
OW2 ASM 3.0 before 9.11 contains a quadratic memory allocation vulnerability in MethodWriter.computeMaxStackAndLocal() and computeAllFrames() when using COMPUTE_MAXS or COMPUTE_FRAMES. Attackers can supply a crafted class file with thousands of overlapping exception handlers, causing excessive Edge allocations and an OutOfMemoryError that crashes the JVM.
