Sicherheitslücken: 10

  1. CVE-2026-112046

    Mittel · CVSS 6.8EPSS 0,12%Korrektur verfügbar

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

    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.

  2. CVE-2026-110591

    Mittel · CVSS 6.8EPSS 0,17%Korrektur verfügbar

    OW2 ASM 1.4.3 before 9.11 Excessive Resource Consumption via Analyzer

    OW2 ASM 1.4.3 before 9.11 contains an excessive resource consumption vulnerability in Analyzer.analyze() that allows attackers to exhaust memory and CPU via crafted class files. Attackers can supply class files analysed through BasicVerifier, SimpleVerifier or SourceInterpreter to trigger unbounded per-instruction Frame allocation and fix point iterations, causing denial of service.

  3. CVE-2026-110270

    Mittel · CVSS 6.8EPSS 0,17%Korrektur verfügbar

    OW2 ASM 3.0 before 9.11 Exponential Memory Allocation in JSRInlinerAdapter

    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.

  4. CVE-2026-110263

    Mittel · CVSS 6.8EPSS 0,17%Korrektur verfügbar

    OW2 ASM 3.0 before 9.11 Uncontrolled Recursion in SignatureReader

    OW2 ASM 3.0 before 9.11 contains an uncontrolled recursion vulnerability in SignatureReader.parseType() that allows attackers to exhaust the stack via deeply nested generic type signatures. Attackers can supply a crafted class file with a long Signature attribute containing many nested type arguments to trigger a StackOverflowError during class transformation, causing denial of service.

  5. CVE-2026-110262

    Mittel · CVSS 4.8EPSS 0,17%Korrektur verfügbar

    OW2 ASM 3.1 before 9.11 Excessive Memory Allocation in AdviceAdapter

    OW2 ASM 3.1 before 9.11 contains an excessive memory allocation vulnerability in the asm-commons AdviceAdapter that allows attackers to exhaust memory by supplying crafted class files. Attackers can craft bytecode with many forward jump targets in constructors, causing unbounded stack copies in forwardJumpStackFrames and allocation of hundreds of megabytes, leading to denial of service.

  6. CVE-2026-110261

    Mittel · CVSS 6.8EPSS 0,17%Korrektur verfügbar

    OW2 ASM 3.0 before 9.11 Excessive CPU Consumption via ClassWriter COMPUTE_FRAMES

    OW2 ASM 3.0 before 9.11 contains a denial of service vulnerability that allows attackers to exhaust CPU by supplying crafted class files processed with ClassWriter.COMPUTE_FRAMES. Attackers can craft methods that make the unbounded MethodWriter.computeAllFrames() fix point algorithm converge slowly, tying up transforming threads for unbounded time.

  7. CVE-2026-110260

    Mittel · CVSS 6.8EPSS 0,17%Korrektur verfügbar

    OW2 ASM 3.0 before 9.11 Quadratic Memory Allocation via Exception Handlers

    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.

  8. CVE-2026-110259

    Mittel · CVSS 6.8EPSS 0,17%Korrektur verfügbar

    OW2 ASM 3.0 before 9.11 Uncontrolled Recursion via ClassWriter.replaceAsmInstructions()

    OW2 ASM 3.0 before 9.11 contains an uncontrolled recursion vulnerability in ClassWriter.replaceAsmInstructions() that allows attackers to cause denial of service through crafted class files. Attackers can supply a class with a large method containing many long forward jumps, triggering unbounded toByteArray() recursion and a StackOverflowError during transformation.

  9. CVE-2026-110258

    Mittel · CVSS 6.8EPSS 0,17%Korrektur verfügbar

    OW2 ASM 3.0 before 9.11 Excessive Memory Allocation via Multiple RET Instructions

    OW2 ASM 3.0 before 9.11 contains an excessive memory allocation vulnerability in Label.addSubroutineRetSuccessors() that fails to enforce the single-RET-per-JSR rule. Attackers can supply a crafted invalid class file with multiple RET instructions for one JSR, triggering a roughly 2 GB allocation that crashes the JVM.

  10. CVE-2026-110257

    Mittel · CVSS 6.8EPSS 0,17%Korrektur verfügbar

    OW2 ASM 5.0 before 9.11 Excessive Memory Allocation via BootstrapMethods Attribute

    OW2 ASM 5.0 before 9.11 contains an excessive memory allocation vulnerability in ClassReader.readBootstrapMethodsAttribute() that sizes an int array from num_bootstrap_methods without validating attribute_length. Attackers can supply a crafted class file of about 100 bytes that forces roughly 2 GB allocation, causing an OutOfMemoryError that crashes the JVM or consuming thread.
