Security readout for executives and security teams
Plain-English summary
A malformed Office document can crash the antivirus scanning process in affected Gen Digital products. The business issue is reduced endpoint protection availability, not data theft or system takeover based on the cited sources. Systems updated to VPS 25020100 or later are reported as not vulnerable.
Executive priority
Treat as a medium-priority endpoint resilience issue. It can reduce antivirus availability on affected systems, especially where untrusted Office files are common, but sources do not show active exploitation or broader compromise impact.
Technical view
CVE-2025-7019 is a CWE-121 stack overflow in antivirus scanning logic for malformed Office Open XML files. It affects listed Avast, AVG, Norton, Avast One, and Avast Business Antivirus products before virus definition build VPS 25020100 across Windows, macOS, and Linux. CVSS 3.1 is 5.5 with local vector, user interaction required, and high availability impact.
Likely exposure
Exposure is likely on endpoints or servers running the listed Gen Digital antivirus products, or products consuming the same shared engine stream, with virus definitions below VPS 25020100.
Exploitation context
The source bundle does not cite active exploitation, and KEV status is false. The described attack requires a malformed Office Open XML file to be scanned. Cited impact is denial-of-service of the antivirus process, with no stated confidentiality or integrity impact.
Researcher notes
Key boundaries are version and update-stream based. Validate definition build, not only product name. The CVSS vector indicates local attack surface, no privileges, required user interaction, unchanged scope, and availability-only impact. Evidence does not support claims of code execution.
Mitigation direction
- Update virus definitions to VPS 25020100 or later.
- Confirm endpoints receive Gen Digital definition updates successfully.
- Prioritize systems handling untrusted Office documents.
- Check Gen Digital advisory for any revised vendor guidance.
Validation and detection
- Inventory affected Gen Digital antivirus products across endpoints.
- Verify each installation reports VPS 25020100 or later.
- Review endpoint logs for antivirus process crashes after Office scans.
- Confirm update failures are remediated and retried.

Stack-based Buffer Overflow
Stack-based Buffer Overflow represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
