CVE-2025-2756
Published: 25 March 2025
Description
Adversaries may exploit software vulnerabilities in client applications to execute code.
Security Summary
CVE-2025-2756 is a heap-based buffer overflow vulnerability in the Open Asset Import Library (Assimp) version 5.4.3. It affects the Assimp::AC3DImporter::ConvertObjectSection function within the file code/AssetLib/AC/ACLoader.cpp, specifically in the AC3D File Handler component. The issue arises from manipulation of the 'tmp' argument, as classified under CWE-119 (Improper Restriction of Operations within the Bounds of a Memory Buffer) and CWE-122 (Heap-based Buffer Overflow). The vulnerability received a CVSS v3.1 base score of 6.3 (AV:N/AC:L/PR:N/UI:R/S:U/C:L/I:L/A:L) and was published on 2025-03-25.
The vulnerability can be exploited remotely by an unauthenticated attacker with no privileges, requiring user interaction such as opening a maliciously crafted AC3D file. Successful exploitation leads to limited impacts on confidentiality, integrity, and availability, potentially allowing arbitrary code execution or denial of service via the buffer overflow.
Advisories and discussions are available in referenced sources, including GitHub issues #6018 and #6018#issue-2877375815, as well as VulDB entries at ctiid.300861, id.300861, and submit.517790. The exploit has been publicly disclosed and may be used.
Notable context includes the public disclosure of the exploit, enabling potential widespread use against applications relying on Assimp for 3D asset parsing.
