CVE-2022-40660
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedThis vulnerability allows remote attackers to execute arbitrary code on affected installations of NIKON NIS-Elements Viewer 1.2100.1483.0. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file. The specific flaw exists within the parsing of PSD images. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a heap-based buffer. An attacker can leverage this vulnerability to execute code in the context of the current process. Was ZDI-CAN-15135.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceHeap-based buffer overflow in NIKON NIS-Elements Viewer when parsing PSD images. The application fails to validate the length of user-supplied data before copying it to a heap buffer, allowing remote code execution via malicious PSD file or page requiring user interaction.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Verify Nikon NIS-Elements Viewer installationCheck for the presence of Nikon NIS-Elements Viewer in the system (typically found in Program Files or Program Files (x86) directory, or search for nikon*.exe or NIS-Elements*.exe)Affected if The application is installed on the system
-
Determine installed versionLocate the executable (commonly named NIS-Elements Viewer.exe or similar) and check its file version property (right-click > Properties > Details > File Version), or use command: wmic datafile where "name like '%NIS-Elements%'" get VersionAffected if Version matches 1.2100.1483.0 exactly
-
Identify PSD file handling capabilityCheck if the application has been used to open or can open PSD (Photoshop Document) files. This may be evident from recent files, file associations, or user workflow documentationAffected if Users process, view, or open PSD image files using this application
-
Confirm PSD parsing feature statusInspect application configuration or registry for PSD import/enable settings if available, or verify through direct testing with a benign PSD fileAffected if PSD file parsing is enabled or accessible through the viewer
System is affected if Nikon NIS-Elements Viewer version 1.2100.1483.0 is installed AND users process PSD image files with the application, as the heap overflow occurs during PSD parsing.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataRestrict handling of untrusted PSD files; update to vendor patch when available; consider compensating controls such as endpoint protection or file sandboxing until vendor fix is released.
