Security readout for executives and security teams
Plain-English summary
A specially crafted document or web page could make Foxit Reader run attacker-controlled code when opened. The victim must interact with malicious content. The sources identify Foxit Reader 9.0.0.29935 as affected, but do not provide CVSS scoring or active exploitation evidence.
Executive priority
Treat this as a high-priority endpoint risk if Foxit Reader 9.0.0.29935 exists in the environment. The business risk is document-triggered code execution, but urgency is moderated by required user interaction and no cited active exploitation evidence.
Technical view
CVE-2018-9982 is a CWE-787 out-of-bounds write in Foxit Reader’s U3D Texture Width parsing. Improper validation of user-supplied data can write past an allocated object and allow code execution in the current process context. ZDI tracks it as ZDI-CAN-5483 / ZDI-18-380.
Likely exposure
Exposure is most likely on endpoints running Foxit Reader 9.0.0.29935, especially where users open external PDFs or visit untrusted web content. The source bundle does not establish other affected versions or products.
Exploitation context
Public sources describe remote code execution requiring user interaction: opening a malicious file or visiting a malicious page. The CVE is not listed as KEV in the bundle, and no cited source here confirms active exploitation.
Researcher notes
The source bundle gives a precise bug class and parser area, but limited remediation detail. Do not extrapolate affected versions beyond Foxit Reader 9.0.0.29935 without vendor confirmation. Focus validation on version discovery and vendor bulletin correlation.
Mitigation direction
- Inventory endpoints for Foxit Reader 9.0.0.29935.
- Check Foxit’s security bulletins for fixed versions or official guidance.
- Prioritize upgrade or removal where the affected version is found.
- Restrict opening untrusted PDFs and embedded 3D content where feasible.
- Use email and web controls to reduce malicious document delivery.
Validation and detection
- Confirm installed Foxit Reader versions across managed endpoints.
- Check vulnerability tooling for CVE-2018-9982 coverage and findings.
- Review EDR alerts involving Foxit Reader child processes or crashes.
- Validate update status against Foxit’s published security bulletin.
- Scope users who routinely handle external PDF attachments.
