Numeric Truncation Error

Overview Affected versions of this package are vulnerable to Numeric Truncation Error in readbrtable in arch/WASM/WASMDisassembler.c. An attacker can cause no-progress disassembly or parser desynchronization by supplying a large, well-formed brtable instruction through csdisasm or csdisasmiter. T...

AZL-95979 CVE-2026-49263 affecting package capstone 4.0.2-4

Capstone is a disassembly framework. Prior to version 6.0.0-Alpha9, Capstone's WebAssembly backend accepts attacker-controlled raw WASM instruction bytes through the public csdisasm and csdisasmiter APIs. For a large but well-formed brtable instruction, the WASM decoder accumulates the immediate...
