Vulnerability Title
cgltf 1.15 Integer Overflow via cgltf_validate() Accessor Bounds Check
Vulnerability Description
cgltf through 1.15 contains an integer overflow vulnerability in the non-sparse accessor bounds check within cgltf_validate() that allows remote attackers to cause memory disclosure and denial of service by supplying crafted accessor count values. Attackers can provide malformed .gltf or .glb input with a specially crafted accessor count to overflow the unsigned integer multiplication of accessor stride and element count, causing the bounds check to pass and triggering a heap out-of-bounds read when cgltf_accessor_read_float() is subsequently called on the validated malformed accessor.

Vulnerability Title
Johannes Kuhlmann cgltf 数字错误漏洞
Vulnerability Description
Johannes Kuhlmann cgltf是德国Johannes Kuhlmann个人开发者开源的一个轻量级单文件glTF模型解析组件。 Johannes Kuhlmann cgltf 1.15及之前版本存在数字错误漏洞,该漏洞源于cgltf_validate()中的非稀疏访问器边界检查存在整数溢出,可能导致远程攻击者通过提供特制的访问器数量值,使无符号整数乘法溢出,导致边界检查通过并触发堆越界读取,造成内存泄露和拒绝服务。
