Security readout for executives and security teams
Plain-English summary
CVE-2022-35067 is a heap buffer overflow in OTFCC's otfccdump component, reported at commit 617837b. A crafted input could crash the tool, causing denial of service. The public record does not identify normalized affected product versions or a fixed release.
Executive priority
Handle as moderate priority unless OTFCC is exposed in automated file-processing services. Business risk is primarily service disruption, not data theft, based on the published CVSS impacts.
Technical view
The CVE describes CWE-787 out-of-bounds write behavior in /release-x64/otfccdump+0x6e41b0. CVSS 3.1 is 6.5 with high availability impact, no confidentiality or integrity impact, no privileges required, and user interaction required. Evidence names commit 617837b but not a vendor advisory or patch.
Likely exposure
Exposure is most likely where OTFCC otfccdump from or near commit 617837b processes untrusted font-related files. The CVE record does not provide CPEs, package names, downstream distributions, or version ranges, so asset matching requires local software inventory and build provenance.
Exploitation context
The source bundle includes public references, including a GitHub PoC page, but KEV is false and no cited source states active exploitation. Treat this as a denial-of-service parsing risk requiring a crafted file and user or workflow interaction.
Researcher notes
The public data is sparse: affected vendor, product, versions, and CPEs are listed as n/a. The CVE names a binary offset and commit, but no official fix is included in the bundle. Do not infer broader OpenType tooling exposure without local evidence.
Mitigation direction
- Check OTFCC project guidance for a fixed commit or release.
- Avoid processing untrusted font files with affected otfccdump builds.
- Run font parsing in isolated, least-privileged environments.
- Add resource limits around automated font ingestion workflows.
- Track upstream issue or advisory updates for remediation details.
Validation and detection
- Inventory systems and pipelines that use OTFCC or otfccdump.
- Identify whether builds derive from commit 617837b.
- Review whether workflows accept untrusted font inputs.
- Check crash telemetry for otfccdump availability failures.
- Confirm any upgraded build against upstream release notes.

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.
