Name of the Vulnerable Software and Affected Versions Open Design Alliance PRC SDK versions prior to 2022.11

Description The issue exists within the parsing of U3D files, specifically due to the incorrect use of the LibJpeg source manager inside the U3D library. Crafted data in a U3D file can trigger a read past the end of an allocated buffer, allowing an attacker to execute code in the context of the current process.

Recommendations For versions prior to 2022.11, update to a version 2022.11 or later to resolve the issue. As a temporary workaround, consider restricting the use of U3D file parsing functionality until a patch is available. Avoid using crafted U3D files that can trigger the out-of-bounds read.

Fix
