Security readout for executives and security teams
Plain-English summary
CVE-2022-35092 is a crash vulnerability in SWFTools tied to commit 772e55a2. A crafted local input can trigger a segmentation violation, causing denial of service. The sources do not show data theft, privilege escalation, or confirmed real-world exploitation.
Executive priority
Prioritize if SWFTools handles external or customer-supplied files in production workflows. Otherwise, this is a moderate availability issue with incomplete product-version data and no confirmed active exploitation in the supplied sources.
Technical view
The CVE describes a segmentation violation in convert_gfxline in /gfxpoly/convert.c, classified as CWE-787. CVSS 3.1 is 5.5 with local attack vector, low complexity, no privileges, required user interaction, and high availability impact only.
Likely exposure
Exposure is most likely where SWFTools builds around commit 772e55a2 process untrusted files through user-driven or local workflows. The source bundle lists no formal vendor, product CPE, affected version range, or packaged distribution details.
Exploitation context
The bundle includes a GitHub issue and a public PoC reference, but CISA KEV status is false. There is no cited evidence of active exploitation in the provided sources, so treat this as plausible denial-of-service risk rather than confirmed in-the-wild activity.
Researcher notes
Evidence is narrow: a commit-specific SWFTools crash report, CWE-787 classification, and CVSS availability impact. Affected vendor, versions, CPEs, and official fix details are not provided. Avoid extrapolating beyond SWFTools commit 772e55a2 without upstream confirmation.
Mitigation direction
- Check upstream SWFTools issue guidance for patched commits or maintainer recommendations.
- Avoid processing untrusted files with affected SWFTools builds until status is confirmed.
- Run SWFTools conversion jobs with least privilege and resource isolation.
- Limit automated ingestion paths that pass external files into SWFTools.
- Monitor crash telemetry for segmentation faults during file conversion.
Validation and detection
- Inventory systems and pipelines using SWFTools or bundled SWFTools binaries.
- Confirm whether builds include commit 772e55a2 or the affected convert.c lineage.
- Review whether SWFTools processes untrusted local files or user-submitted inputs.
- Check crash logs for convert_gfxline or /gfxpoly/convert.c failures.
- Track the referenced GitHub issue for fix status and affected-version clarification.
