Description Summary:
An integer overflow vulnerability in libbiosig's ABF parsing functionality allows attackers to execute arbitrary code via a specially crafted ABF file.
Executive Summary:
A critical integer overflow vulnerability in The Biosig Project libbiosig allows remote attackers to execute arbitrary code through malicious ABF files.
Vulnerability Details
CVE-ID: CVE-2025-53518
Affected Software: The Biosig Project libbiosig
Affected Versions: 3.9.0 and Master Branch (35a819fa)
Vulnerability: This is an integer overflow flaw within the ABF file parsing logic. It can be triggered by an unauthenticated attacker providing a maliciously crafted file, potentially leading to arbitrary code execution.
Business Impact
The ability to execute arbitrary code poses a severe risk to system integrity and data confidentiality. Given the CVSS score of 9.8, this vulnerability is classified as critical, as it could allow full system compromise, unauthorized data access, and persistent malware installation.
Remediation Plan
Immediate Action: Identify systems running the affected versions of libbiosig and ensure they are updated to the latest available release as provided by the vendor.
Proactive Monitoring: Monitor system logs for unusual file parsing errors or unexpected process crashes that may indicate an attempt to trigger the overflow.
Compensating Controls: If patching is delayed, implement strict input validation or sandboxing for any application processing ABF files to prevent the ingestion of malicious inputs.
Exploitation Status
Public Exploit Available: Unknown
Analyst Notes: As of Aug 25, 2025, there is no public information indicating active exploitation of this vulnerability. However, due to the nature of the flaw, the potential for exploitation is high.
Analyst Recommendation
This vulnerability represents a significant risk due to the potential for remote code execution. Security teams should prioritize patching libbiosig installations immediately to mitigate the risk of unauthorized system access and compromise.
