Withsecure Atlant with Capricorn engine before 2025-01-20_02 allows a Remote Denial of Service via an out-of-bounds memory read during processing of a document file by the antivirus engine.
AI Analysis
Technical Summary
WithSecure Atlant with the Capricorn engine versions prior to 2025-01-20_02 contain an out-of-bounds memory read vulnerability (CWE-125) that can be triggered remotely by processing a malicious document file. This vulnerability results in a denial of service (DoS) condition by causing the antivirus engine to read memory outside its intended bounds. The CVSS v3.1 base score is 3.7, reflecting low severity with network attack vector, high attack complexity, no privileges required, no user interaction, and impact limited to availability.
Potential Impact
Successful exploitation causes a remote denial of service by crashing or destabilizing the antivirus engine during document file processing. There is no impact on confidentiality or integrity. No active exploitation is known.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, consider restricting document file processing from untrusted sources or using alternative scanning methods to reduce exposure.
