Name of the Vulnerable Software and Affected Versions: JT2Go versions prior to V13.1.0 Teamcenter Visualization versions prior to V13.1.0

Description: A vulnerability has been identified in the affected applications, where they lack proper validation of user-supplied data when parsing SGI and RGB files. This could result in an out of bounds write past the end of an allocated structure, allowing an attacker to execute code in the context of the current process.

Recommendations: For JT2Go versions prior to V13.1.0, update to version V13.1.0 or later to resolve the issue. For Teamcenter Visualization versions prior to V13.1.0, update to version V13.1.0 or later to resolve the issue. As a temporary workaround, consider restricting the parsing of SGI and RGB files until a patch is available.
