CVE-2020-27005
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 < V13.1.0.1), Teamcenter Visualization (All versions < V13.1.0.1). Affected applications lack proper validation of user-supplied data when parsing of TGA files. This could result in an out of bounds write past the end of an allocated structure. An attacker could leverage this vulnerability to execute code in the context of the current process. (ZDI-CAN-12178)
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 confidenceThe vulnerability exists in the TGA file parsing functionality of JT2Go and Teamcenter Visualization. Affected versions lack proper validation of user-supplied data when parsing TGA files, leading to an out-of-bounds write past the end of an allocated structure. This memory corruption can be leveraged by an attacker to achieve code execution in the context of the current process.

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 productCheck for Siemens JT2Go or Teamcenter Visualization installation by looking in program directories (typically C:\Program Files\Siemens\ or C:\Program Files (x86)\Siemens\) or via Windows Add/Remove ProgramsAffected if Either product is installed
-
Determine JT2Go versionIf JT2Go is installed, right-click the executable (JT2Go.exe), select Properties, then go to the Details tab to view the File VersionAffected if Version is lower than 13.1.0.1
-
Determine Teamcenter Visualization versionIf Teamcenter Visualization is installed, right-click the main executable (such as TeamcenterVisualization.exe or associated binaries), select Properties, then check the File Version in the Details tabAffected if Version is lower than 13.1.0.1
-
Confirm TGA parsing usageReview whether the software has been used to open or process TGA image files, as the vulnerability is triggered during TGA file parsingAffected if TGA files have been opened with the affected software version
You are affected if you have JT2Go or Teamcenter Visualization installed with a version lower than 13.1.0.1 and have opened TGA files with the software.

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 data13.1.0.1
Upgrade JT2Go and Teamcenter Visualization to version V13.1.0.1 or later. Until patched, avoid opening untrusted TGA files from unknown or untrusted sources.
