CVE-2022-34215: Adobe Acrobat Reader DC Annotation Polygon Out-Of-Bounds Read Remote Code Execution Vulnerability

Adobe Acrobat Reader versions 22.001.20142 (and earlier), 20.005.30334 (and earlier) and 17.012.30229 (and earlier) are affected by an out-of-bounds read vulnerability when parsing a crafted file, which could result in a read past the end of an allocated memory structure. An attacker could leverage this vulnerability to execute code in the context of the current user. 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 vulnerability affects Adobe Acrobat Reader when opening a specially crafted file. If a user opens the malicious file, an attacker could run code with that user’s permissions. The main business risk is compromise of workstations through document-based phishing or file sharing.

Executive priority

Treat this as a high-priority endpoint patching issue. It needs user interaction, but document-based attacks are common and Acrobat Reader is widely deployed. Patch exposed workstations through normal emergency or accelerated desktop update channels.

Technical view

CVE-2022-34215 is a CWE-125 out-of-bounds read in Adobe Acrobat Reader file parsing. Adobe lists Reader versions 22.001.20142 and earlier, 20.005.30334 and earlier, and 17.012.30229 and earlier as affected. Successful exploitation requires user interaction and may allow code execution as the current user.

Likely exposure

Exposure is most likely on endpoints running affected Adobe Acrobat Reader versions, especially users who receive PDFs or documents from email, web downloads, partners, or shared drives. Systems with least-privilege user accounts have reduced blast radius but are still at risk.

Exploitation context

The supplied bundle does not show CISA KEV listing or cited evidence of active exploitation. Exploitation requires a victim to open a malicious file, so phishing and document delivery are the practical concern, not unauthenticated network exploitation.

Researcher notes

The record describes an out-of-bounds read during crafted-file parsing with CVSS 7.8 and full confidentiality, integrity, and availability impact. The bundle does not provide proof-of-concept details, exploit telemetry, or low-level parser internals, so validation should focus on product version exposure and vendor bulletin alignment.

Mitigation direction

  • Apply Adobe guidance from APSB22-32 for affected Acrobat Reader installations.
  • Update Reader beyond the affected versions listed in the CVE source bundle.
  • Prioritize endpoints used for email, document intake, legal, finance, and customer support workflows.
  • Limit standard users’ local privileges to reduce impact of user-context code execution.
  • Use attachment filtering and user awareness controls for unsolicited document files.

Validation and detection

  • Inventory Acrobat Reader versions across managed endpoints.
  • Flag Reader versions 22.001.20142, 20.005.30334, 17.012.30229, and earlier.
  • Confirm Adobe APSB22-32 remediation has been applied where applicable.
  • Review EDR and email telemetry for suspicious document-driven execution around exposed users.
  • Verify users do not run daily work under local administrator accounts.

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.
