CVE-2026-110257 (GCVE-0-2026-110257)

Vulnerability from nvd – Published: 2026-10-14 14:16 – Updated: 2026-10-14 15:55

Title

OW2 ASM 5.0 before 9.11 Excessive Memory Allocation via BootstrapMethods Attribute

Summary

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.

CVE-2026-110263 (GCVE-0-2026-110263)

Vulnerability from cvelistv5 – Published: 2026-10-14 14:16 – Updated: 2026-10-14 16:12

Title

OW2 ASM 3.0 before 9.11 Uncontrolled Recursion in SignatureReader

Summary

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.

CVE-2026-110257 (GCVE-0-2026-110257)

Vulnerability from cvelistv5 – Published: 2026-10-14 14:16 – Updated: 2026-10-14 15:55

Title

OW2 ASM 5.0 before 9.11 Excessive Memory Allocation via BootstrapMethods Attribute

Summary

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.

Severity
