CVE-2025-7003

Local code execution via malformed PDF scan

Published Jun 12, 2026 · Updated Jun 12, 2026

Out-of-bounds read in the Gen Digital Avira Antivirus engine before 8.3.70.56 allows local users to execute code or crash the engine via a malformed PDF. The PDF scanner reads beyond a heap buffer while processing malformed file data; Gen Digital has not disclosed the affected routine or field. Exploitation requires user interaction that causes the engine to scan the file, and the resulting compromise or crash is confined to the antivirus engine process.
