CVE-2020-26985
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 · uneditedA vulnerability has been identified in JT2Go (All versions < V13.1.0), Teamcenter Visualization (All versions < V13.1.0). Affected applications lack proper validation of user-supplied data when parsing of RGB and SGI files. This could result in a heap-based buffer overflow. An attacker could leverage this vulnerability to execute code in the context of the current process. (ZDI-CAN-11986, ZDI-CAN-11994)
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 confidenceJT2Go and Teamcenter Visualization fail to validate user-supplied data when parsing RGB and SGI image files, leading to a heap-based buffer overflow. An attacker can exploit this by convincing a user to open a specially crafted file, achieving code execution within the application's 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.
-
Identify installed JT2Go versionOpen JT2Go, then navigate to Help > About JT2Go, or check the program's properties in Windows Explorer (right-click the executable > Properties > Details tab). Look for the 'Product version' field.Affected if The displayed version is below 13.1.0 (e.g., 13.0.x, 12.x, etc.)
-
Identify installed Teamcenter Visualization versionOpen Teamcenter Visualization, then navigate to Help > About, or check the program's properties in Windows Explorer. Look for the version number in the product information.Affected if The displayed version is below 13.1.0 (e.g., 13.0.x, 12.x, etc.)
-
Check for recent RGB or SGI image filesSearch the file system for files with .rgb or .sgi extensions, particularly in directories where untrusted or downloaded files are stored (e.g., Downloads folder, shared network locations).Affected if Users have recently opened or imported .rgb or .sgi files into the vulnerable software, indicating potential exploitation context.
-
Verify application crash or suspicious behavior logsCheck Windows Event Viewer for application crash events related to JT2Go or Teamcenter Visualization, or review any crash dump files in the application logs directory.Affected if Unexpected crashes occur when opening image files, which may indicate exploitation attempts.
A user is affected if they have JT2Go or Teamcenter Visualization installed with a version number lower than 13.1.0 and have opened or are likely to open RGB or SGI image files.

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 data13.1.0
Upgrade JT2Go and Teamcenter Visualization to version 13.1.0 or later. Until patched, avoid opening untrusted RGB or SGI files from unknown sources.
