A vulnerability, which was classified as critical, has been found in Open Asset Import Library Assimp 5.4.3. Affected by this issue is the function Assimp::LWO::AnimResolver::UpdateAnimRangeSetup of the file code/AssetLib/LWO/LWOAnimation.cpp of the component LWO File Handler. The manipulation leads to heap-based buffer overflow. It is possible to launch the attack on the local host. The exploit has been disclosed to the public and may be used.
The product performs operations on a memory buffer, but it reads from or writes to a memory location outside the buffer's intended boundary. This may result in read or write operations on unexpected memory locations that could be linked to other variables, data structures, or internal program data.
