CVE-2023-29274
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 · uneditedAdobe Substance 3D Painter versions 8.3.0 (and earlier) is affected by an out-of-bounds read vulnerability when parsing a crafted file, which could result in a read past the end of an allocated memory structure. An attacker could leverage this vulnerability to execute code in the context of the current user. Exploitation of this issue requires user interaction in that a victim must open a malicious file.
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 confidenceAdobe Substance 3D Painter contains an out-of-bounds read vulnerability when parsing crafted files. The application reads past the end of an allocated memory buffer during file parsing, which can be leveraged to leak memory contents and potentially achieve code execution in the context of the current user. Exploitation requires a victim to open a malicious file.

Alternatively, check the version in the uninstall registry entry or the application's Info.plist file on macOS.Affected if The displayed version is 8.3.0 or lower.
-
Verify file parsing is accessibleConfirm the application can open project files (.spproj) or supported asset files. Attempt to open a benign test file or verify the File > Open menu option is available and functional.Affected if The application can open and parse project files, making the vulnerability reachable.
-
Check for recent application executionReview system logs or the Windows Event Viewer under Applications for recent executions of Adobe Substance 3D Painter, or check the application's recent files list if accessible.Affected if The application has been recently used to open files, indicating potential exposure to the vulnerability.
