An improper array index validation vulnerability exists in the stl_fix_normal_directions functionality of ADMesh Master Commit 767a105 and v0.98.4. A specially-crafted stl file can lead to a heap buffer overflow. An attacker can provide a malicious file to trigger this vulnerability.

vox2mesh 1.0 has stack-overflow in main.cpp, this is stack-overflow caused by incorrect use of memcpy() funciton. The flow allows an attacker to cause a denial of service (abort) via a crafted file.

ADMesh through 0.98.4 has a heap-based buffer over-read in stl_update_connects_remove_1 (called from stl_remove_degenerate) in connect.c in libadmesh.a.

The transferProxy and approveProxy functions of a smart contract implementation for SmartMesh (SMT), an Ethereum ERC20 token, allow attackers to accomplish an unauthorized transfer of digital assets because replay attacks can occur with the same-named functions (with the same signatures) in other tokens: First (FST), GG Token (GG), M2C Mesh Network (MTC), M2C Mesh Network (mesh), and UG Token (UGT).
