Security readout for executives and security teams
Plain-English summary
This flaw lets a malicious InDesign file trigger memory corruption when opened. If successful, code runs with the logged-in user's rights, which could expose files, modify work, or install malware. It requires user interaction: the victim must open a malicious file.
Executive priority
Treat this as a high-priority workstation patching issue for creative and marketing teams. Urgency is meaningful because compromise can run as the user, but it is not wormable and requires opening a malicious file.
Technical view
CVE-2022-34247 is a CWE-787 out-of-bounds write in Adobe InDesign font parsing. Affected versions are InDesign 17.2.1 and earlier, and 16.4.1 and earlier. CVSS 3.0 is 7.8, with local attack vector, no privileges required, user interaction required, and high confidentiality, integrity, and availability impact.
Likely exposure
Exposure is likely limited to endpoints where Adobe InDesign is installed, especially users who receive or open external design files. The source bundle does not identify server-side exposure or browserless exploitation.
Exploitation context
The supplied sources do not show CISA KEV listing or active exploitation evidence. Exploitation requires a crafted malicious file and a user opening it in an affected InDesign version.
Researcher notes
The record identifies font parsing and out-of-bounds write, but does not provide deeper root-cause details, proof-of-concept status, or fixed build numbers in the provided bundle. Avoid asserting exploitation beyond the user-interaction file-open scenario.
Mitigation direction
- Update Adobe InDesign according to Adobe APSB22-30 guidance.
- Prioritize users handling external InDesign or font-heavy files.
- Restrict opening unsolicited design files from untrusted sources.
- Use endpoint protections to detect suspicious child processes from InDesign.
Validation and detection
- Inventory endpoints with Adobe InDesign installed.
- Confirm installed versions are newer than affected 17.2.1 or 16.4.1 lines.
- Review Adobe APSB22-30 for vendor remediation details.
- Check security telemetry for unusual activity involving InDesign processes.

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