Doc Text:
A flaw was found in Open Asset Import Library Assimp. A remote attacker could exploit a heap-based buffer overflow vulnerability, which occurs when a program writes more data to a memory block than it was intended to hold. This specific flaw exists within the Assimp::Compression::decompressBlock function during file compression decompression. By sending a specially crafted input, an attacker could potentially cause the application to crash (denial of service), disclose sensitive information, or execute arbitrary code.

Description OSIDB Bzimport 2026-08-17 00:51:31 UTC 
A security flaw has been discovered in Open Asset Import Library Assimp 17c12da. Impacted is the function Assimp::Compression::decompressBlock of the file code/Common/Compression.cpp of the component File Parser. Performing a manipulation results in heap-based buffer overflow. The attack may be initiated remotely. The exploit has been released to the public and may be used for attacks. The project was informed of the problem early through an issue report but has not responded yet.
