CVE-2022-35669: Adobe Acrobat Reader DC Font Parsing Out-Of-Bounds Read Information Disclosure Vulnerability

Acrobat Reader versions 22.001.20142 (and earlier), 20.005.30334 (and earlier) and 20.005.30334 (and earlier) are affected by an out-of-bounds read vulnerability that could lead to disclosure of sensitive memory. An attacker could leverage this vulnerability to bypass mitigations such as ASLR. Exploitation of this issue requires user interaction in that a victim must open a malicious file.

Security readout for executives and security teams

Plain-English summary

This flaw lets a malicious PDF cause Adobe Acrobat Reader to read memory it should not. That may expose sensitive memory and help bypass protections such as ASLR. It requires someone to open a crafted file, so email and document-handling workflows are the main concern.

Executive priority

Treat this as a routine but timely endpoint patching issue. It is not documented as actively exploited in the provided sources, but it can support sensitive memory disclosure when users open malicious PDFs.

Technical view

CVE-2022-35669 is a CWE-125 out-of-bounds read in Acrobat Reader font parsing. The CVSS 3.1 score is 5.5: local attack vector, low complexity, no privileges, required user interaction, high confidentiality impact, and no integrity or availability impact.

Likely exposure

Organizations are exposed where Adobe Acrobat Reader versions 22.001.20142 and earlier or 20.005.30334 and earlier remain in use, especially on endpoints that receive external PDFs.

Exploitation context

The provided sources do not show CISA KEV listing or confirmed active exploitation. Exploitation requires user interaction: a victim must open a malicious file. The documented impact is sensitive memory disclosure and possible mitigation bypass support.

Researcher notes

Evidence identifies font parsing, CWE-125, and ASLR bypass potential, but the bundle does not include detailed root cause or fixed build tables. Avoid assuming exploit availability; validate exact affected and fixed tracks from Adobe APSB22-32.

Mitigation direction

  • Update Acrobat Reader according to Adobe APSB22-32 guidance.
  • Inventory endpoints for affected Acrobat Reader versions.
  • Prioritize users who handle external or unsolicited PDFs.
  • Use email and web controls to reduce malicious PDF delivery.
  • Check Adobe guidance for supported fixed versions and deployment details.

Validation and detection

  • Confirm installed Acrobat Reader versions against the CVE and Adobe advisory.
  • Verify patched endpoints report versions newer than the affected release thresholds.
  • Review security controls for externally sourced PDF handling.
  • Check vulnerability scanner findings for CVE-2022-35669 after patching.

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.
