CVE-2025-64736 Vulnerability Summary

CVE-2025-64736: An out-of-bounds read vulnerability exists in the ABF parsing functionality of The Biosig Project libbiosig 3.9.2 and Master Branch (5462afb0). A specially crafted .abf file can lead to an information leak. An attacker can provide a malicious file to trigger this vulnerability.

Assessing the Risk of CVE-2025-64736

Access Complexity Graph

The exploitability of CVE-2025-64736 depends on two key factors: attack complexity (the level of effort required to execute an exploit) and privileges required (the access level an attacker needs).

Exploitability Analysis for CVE-2025-64736

With low attack complexity and no required privileges, CVE-2025-64736 is an easy target for cybercriminals. Organizations should prioritize immediate mitigation measures to prevent unauthorized access and data breaches.

Understanding AC and PR

A lower complexity and fewer privilege requirements make exploitation easier. Security teams should evaluate these aspects to determine the urgency of mitigation strategies, such as patch management and access control policies.

Attack Complexity (AC) measures the difficulty in executing an exploit. A high AC means that specific conditions must be met, making an attack more challenging, while a low AC means the vulnerability can be exploited with minimal effort.

Privileges Required (PR) determine the level of system access necessary for an attack. Vulnerabilities requiring no privileges are more accessible to attackers, whereas high privilege requirements limit exploitation to authorized users with elevated access.

CVSS Score Breakdown Chart

Above is the CVSS Sub-score Breakdown for CVE-2025-64736, illustrating how Base, Impact, and Exploitability factors combine to form the overall severity rating. A higher sub-score typically indicates a more severe or easier-to-exploit vulnerability.

CIA Impact Analysis

Below is the Impact Analysis for CVE-2025-64736, showing how Confidentiality, Integrity, and Availability might be affected if the vulnerability is exploited. Higher values usually signal greater potential damage.

  • Confidentiality: High
    Exploiting CVE-2025-64736 can result in unauthorized access to sensitive data, severely compromising data privacy.
  • Integrity: None
    CVE-2025-64736 poses no threat to data integrity.
  • Availability: Low
    CVE-2025-64736 may slightly degrade system performance without fully affecting service availability.

CWE-125

CAPEC Common Attack Pattern Enumeration and Classification

  • Overread Buffers CAPEC-540 An adversary attacks a target by providing input that causes an application to read beyond the boundary of a defined buffer. This typically occurs when a value influencing where to start or stop reading is set to reflect positions outside of the valid memory location of the buffer. This type of attack may result in exposure of sensitive information, a system crash, or arbitrary code execution.
