Security readout for executives and security teams
Plain-English summary
CVE-2018-9976 affects Foxit Reader 9.0.0.29935. A malicious webpage or file could make Reader read memory outside an expected object while handling U3D texture data. Sources describe sensitive information disclosure and note it may support code execution when chained with other vulnerabilities.
Executive priority
Treat as a targeted document-handling risk, especially in environments where users receive external PDFs. It is not confirmed as actively exploited in the supplied sources, but outdated Reader installations should be removed or upgraded.
Technical view
The flaw is a CWE-125 out-of-bounds read in parsing Texture objects in U3D files. Missing validation of user-supplied data can cause a read past an allocated object inside the Foxit Reader process. It was tracked by ZDI as ZDI-CAN-5425 and ZDI-18-374.
Likely exposure
Exposure is limited to systems running Foxit Reader 9.0.0.29935 that open untrusted PDF-related content or browse attacker-controlled content handled by Reader.
Exploitation context
User interaction is required: the target must visit a malicious page or open a malicious file. The provided sources do not state active exploitation, and CISA KEV status is false.
Researcher notes
The record lacks CVSS data and does not name a specific fixed version in the supplied bundle. Analysis should stay tied to Foxit Reader 9.0.0.29935, U3D Texture parsing, CWE-125, and the ZDI advisory.
Mitigation direction
- Identify and remove Foxit Reader 9.0.0.29935 where still present.
- Check Foxit security bulletins for the vendor-supported fixed version or upgrade guidance.
- Restrict opening untrusted PDF or U3D-containing content until remediated.
- Use endpoint controls to reduce exposure to unsolicited document attachments.
Validation and detection
- Inventory endpoints for Foxit Reader 9.0.0.29935.
- Confirm whether any managed software baselines still include this version.
- Review email and web controls for handling untrusted document content.
- Check vendor advisory records before declaring remediation complete.

Out-of-bounds Read
Out-of-bounds Read represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
