Description Jeremy Choi 2026-07-06 06:43:36 UTC
Disclaimer: Community trackers are created by Red Hat Product Security team on a best effort basis. Package maintainers are required to ascertain if the flaw indeed affects their package, before starting the update process.

A vulnerability was determined in Open Asset Import Library Assimp up to 6.0.4. Affected is the function Assimp::Exporter::ExportToBlob of the file code/AssetLib/Ply/PlyLoader.cpp of the component PLY Model Handler. This manipulation causes double free. The attack can be initiated remotely. The exploit has been publicly disclosed and may be utilized. The project was informed of the problem early through an issue report.
