Code execution via image parser out-of-bounds write
Published Dec 20, 2021 · Updated Apr 23, 2025
Out-of-bounds write in Adobe Dimension 3.4.3 and earlier allows attackers to execute code through a malicious image file. ZDI attributes the flaw to inadequate validation in the PCX parser, which writes past an allocated structure; Adobe's CVE description instead identifies a malicious GIF file. Exploitation requires a user to open the file or visit attacker-controlled content, and resulting code runs in the current process context.

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 <=3.4.3
- Affected versionversion=unspecified <=None
