Code execution via font parser heap overflow
Published Jun 16, 2022 · Updated Apr 23, 2025
Heap-based buffer overflow in Adobe InCopy 17.2 and earlier and 16.4.1 and earlier allows attackers to execute code via a malicious file. The font parser writes beyond an allocated heap buffer while processing crafted font data; Adobe has not disclosed the specific function. A victim must open the file, after which code runs with the privileges of the current user on Windows or macOS.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
- Affected versionversion=unspecified <=16.4.1
- Affected versionversion=unspecified <=17.2
- Affected versionversion=unspecified <=None
