CVE-2022-34252: Adobe InCopy Font Parsing Out-Of-Bounds Read Information Disclosure Vulnerability

Adobe InCopy versions 17.2 (and earlier) and 16.4.1 (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

CVE-2022-34252 is a memory disclosure flaw in Adobe InCopy. A user must open a malicious file, which limits broad remote risk, but successful exploitation could expose sensitive memory and help bypass defenses such as ASLR.

Executive priority

Treat this as a moderate endpoint risk. Prioritize patching for creative, publishing, and marketing users who routinely handle external files, but it is not documented as actively exploited in the provided sources.

Technical view

Adobe InCopy 17.2 and earlier, and 16.4.1 and earlier, contain a CWE-125 out-of-bounds read in font parsing. The CVSS 3.1 score is 5.5, with local attack vector, required user interaction, and high confidentiality impact.

Likely exposure

Exposure is most likely on endpoints where Adobe InCopy is installed and users open externally supplied documents or font-bearing content. The provided CPE data is incomplete, so version inventory is necessary.

Exploitation context

The source bundle does not show CISA KEV listing or active exploitation evidence. Exploitation requires victim interaction by opening a malicious file. The documented outcome is memory disclosure, potentially supporting mitigation bypass.

Researcher notes

Evidence supports a font-parsing out-of-bounds read with confidentiality impact only. Fixed version details and exploit availability are not included in the supplied bundle, so avoid claiming more than Adobe advisory coverage and CVE metadata support.

Mitigation direction

  • Inventory Adobe InCopy installations and identify versions 17.2 or earlier and 16.4.1 or earlier.
  • Review Adobe APSB22-29 and apply vendor-provided InCopy security updates where applicable.
  • Restrict opening of untrusted InCopy documents and files from unknown sources.
  • Use endpoint controls to quarantine suspicious document attachments before user access.

Validation and detection

  • Confirm installed Adobe InCopy versions across managed endpoints.
  • Verify affected systems have received the applicable Adobe advisory update.
  • Check endpoint telemetry for unusual InCopy crashes after opening external files.
  • Review mail and file-sharing controls for untrusted document delivery paths.

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.
