CVE-2025-15647— CDT before 1.4.5 Out-of-Bounds Read via opposedVertexInd

Quick assessment

Affected
artem-ogre CDT
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

CDT 1.4.5 之前版本中存在一个越界读取漏洞，位于 函数中。当以浮点数计算约束边的交点，且交点舍入后落在相邻三角形之外时，会触发该漏洞。攻击者可以通过几何数据提供近乎退化的约束边，从而引发越界数组访问，导致调用该函数的进程崩溃。

Vulnerability Title
CDT before 1.4.5 Out-of-Bounds Read via opposedVertexInd
Source: CVE Program / CVE List V5
Vulnerability Description
CDT before 1.4.5 contains an out-of-bounds read vulnerability in the opposedVertexInd() function when constraint edge intersections are computed in floating point and round outside adjacent triangles. Attackers can supply nearly-degenerate constraint edges through geometry data to trigger an out-of-bounds array access that crashes the calling process.
