DescriptionNVD
A stack overflow in the experimental/tinyobj_loader_opt.h file of tinyobjloader commit d56555b allows attackers to cause a Denial of Service (DoS) via supplying a crafted .mtl file.
AnalysisAI
Stack overflow in tinyobjloader's experimental MTL file parser (tinyobj_loader_opt.h) allows local attackers to trigger denial of service by supplying a malformed .mtl file. The vulnerability affects the library's material file parsing logic and crashes the application via stack memory corruption, though with EPSS score of 0.01% and no confirmed active exploitation, real-world risk is minimal despite the moderate CVSS 6.2 rating.
