CVE-2025-2584
Description
A flaw was found in WebAssembly WABT's BinaryReaderInterp component. This vulnerability allows remote attackers to cause a heap-based buffer overflow and potentially crash the application via specially crafted WebAssembly files lacking proper formatting, due to missing boundary checks in the GetReturnCallDropKeepCount function.
Mitigation
Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base or stability.
Common Vulnerability Scoring System (CVSS) Score Details
Info alert:Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).
The following CVSS metrics and score provided are preliminary and subject to review.
