Security readout for executives and security teams
Plain-English summary
CVE-2022-35672 is a high-severity Adobe Acrobat Reader flaw. A malicious document can trigger a memory parsing error and may let an attacker run code as the signed-in user. The victim must open the malicious file, so exposure is mainly endpoint users who handle untrusted PDFs or attachments.
Executive priority
Treat as a near-term endpoint patching priority. It can lead to code execution, but it requires a user to open a malicious file and the supplied sources do not show confirmed active exploitation.
Technical view
Adobe Acrobat Reader versions 22.001.20085 and earlier, 20.005.30314 and earlier, and 17.012.30205 and earlier contain a CWE-125 out-of-bounds read while parsing a crafted file. The CVSS 3.0 score is 7.8, with local attack vector, no privileges required, user interaction required, and high confidentiality, integrity, and availability impact.
Likely exposure
Organizations are exposed where affected Adobe Acrobat Reader versions remain on desktops or VDI images, especially for users opening email attachments, downloaded PDFs, or externally supplied documents. The provided sources do not identify server-side exposure.
Exploitation context
The sources state exploitation requires user interaction: a victim must open a malicious file. The CVE is not listed as KEV in the supplied bundle, and no cited source in the bundle confirms active exploitation.
Researcher notes
The CVE record ties the issue to crafted-file parsing and CWE-125 out-of-bounds read. The exact vulnerable parser details, exploit primitives, and fixed build numbers are not provided in the supplied bundle beyond the Adobe advisory reference.
Mitigation direction
- Apply Adobe security update guidance from APSB22-16.
- Prioritize endpoints running affected Acrobat Reader versions.
- Restrict opening untrusted PDFs until updates are verified.
- Use least-privilege user accounts where practical.
- Check Adobe guidance for any additional supported mitigations.
Validation and detection
- Inventory Acrobat Reader versions across managed endpoints.
- Flag versions at or below 22.001.20085, 20.005.30314, or 17.012.30205.
- Confirm patched versions align with Adobe APSB22-16 guidance.
- Review endpoint telemetry for suspicious document-open events.
- Verify PDF handling policies for high-risk user groups.

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.
