Application denial-of-service via crafted-file null dereference
Published Mar 16, 2022 · Updated Apr 23, 2025
NULL pointer dereference in Adobe Bridge 11.1.1 and earlier allows remote attackers to interrupt the application through a crafted file. Adobe identifies file parsing as the vulnerable locus but does not disclose the parser or the unchecked pointer operation that triggers the dereference. A victim must open the malicious file, and the documented consequence is limited to denial of service in the current user's application 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 <=11.1.1
