CVE-2022-42946
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 · uneditedParsing a maliciously crafted X_B and PRT file can force Autodesk Maya 2023 and 2022 to read beyond allocated buffer. This vulnerability in conjunction with other vulnerabilities could lead to code execution in the context of the current process.
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 confidenceAutodesk Maya 2022 and 2023 contain an out-of-bounds read vulnerability when parsing maliciously crafted X_B and PRT files. The parser reads beyond allocated buffer boundaries, which when chained with other vulnerabilities could enable arbitrary code execution in the process context.

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.
-
Confirm Maya installationLook for Maya installation directory (typically C:\Program Files\Autodesk\Maya2023 on Windows or /Applications/Autodesk/Maya2023 on macOS)Affected if Maya 2023 is installed on the system
-
Identify installed Maya versionRun 'maya.exe -version' from the Maya bin directory, or check the version info of the Maya executable in the installation folderAffected if The reported version matches 2023 (or 2022 if vulnerable)
-
Verify X_B file handler existsCheck for the existence of file format plugins or handlers that process X_B files in the Maya plug-in or bin directoriesAffected if X_B file import capability is present in the Maya installation
-
Verify PRT file handler existsCheck for the existence of file format plugins or handlers that process PRT files (commonly used for Pixar's RenderMan texture format) in the Maya plug-in or bin directoriesAffected if PRT file import capability is present in the Maya installation
The system is affected if Maya 2023 (or 2022) is installed with X_B or PRT file parsing functionality enabled and the version falls within the unpatched affected range.

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 dataApply the vendor patch from Autodesk when released. Until then, restrict acceptance of X_B and PRT files from untrusted sources and consider running Maya in sandboxed or isolated environments to limit potential impact.
