Open Asset Import Library Assimp ASE File ASEParser.cpp ParseLV4MeshBonesVertices heap-based overflow
Noroxi assessment
Priority: Monitor (action score 19/100)
- The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
- Probability of exploitation in the next 30 days: 0.32% (FIRST EPSS).
- Someone with local access to the system can trigger it. A low-privileged account is enough. No user action is required. No special conditions are required; it is repeatable.
- Fixed version: assimp (Debian:14) 6.0.2+ds-1; assimp (openSUSE:Tumbleweed) 6.0.1-1.1; qt5-qt3d (Red Hat:enterprise_linux:9::appstream) 0:5.15.9-2.el9_6.
Low priority for now. Upgrade to assimp (Debian:14) 6.0.2+ds-1; assimp (openSUSE:Tumbleweed) 6.0.1-1.1; qt5-qt3d (Red Hat:enterprise_linux:9::appstream) 0:5.15.9-2.el9_6 or later.
Generated automatically from the record's data: CVSS (NVD and CNA), CISA KEV and SSVC, FIRST EPSS, exploit sources, fixed versions. How we calculate it
Primary sources: NVD · CVE.org · FIRST EPSS
A vulnerability, which was classified as critical, was found in Open Asset Import Library Assimp 5.4.3. This affects the function Assimp::ASE::Parser::ParseLV4MeshBonesVertices of the file code/AssetLib/ASE/ASEParser.cpp of the component ASE File Handler. The manipulation leads to heap-based buffer overflow. The attack needs to be approached locally. The exploit has been disclosed to the public and may be used. The identifier of the patch is e8a6286542924e628e02749c4f5ac4f91fdae71b. It is recommended to apply a patch to fix this issue.
