org.ow2.asm/asm: OW2 ASM: Denial of Service via infinite loop in Label.resolve()

A flaw was found in OW2 ASM. An attacker can cause a Denial of Service DoS by supplying a specially crafted Java class file with methods that grow beyond 64 kilobytes during transformation. When processing this file, an offset truncation error triggers an infinite loop within the method resolutio...

CVE-2026-110263

A flaw was found in OW2 ASM. An attacker could cause a Denial of Service DoS by providing a specially crafted Java class file containing deeply nested generic type signatures. When the library parses these signatures using the SignatureReader component, uncontrolled recursion exhausts available...

CVE-2026-110258

A flaw was found in OW2 ASM. An attacker could cause a Denial of Service DoS by providing a specially crafted, invalid Java class file. Due to improper validation of subroutine instructions, processing the file triggers excessive memory allocation, causing the Java Virtual Machine JVM to crash...

CVE-2026-110261

A flaw was found in OW2 ASM. An attacker can supply a specially crafted class file to an application that analyzes or transforms bytecode with automatic stack map frame computation enabled. This causes an internal computation algorithm to take an excessive amount of time to complete, consuming hi...

CVE-2026-110260

A flaw was found in OW2 ASM. An attacker can trigger a Denial of Service DoS by providing a specially crafted Java class file containing numerous overlapping exception handlers. When the library analyzes the method stack or frame structures of such a file, it performs excessive memory allocation,...
