CVE-2025-15647: Artem-Ogre Cdt

Medium severity, CVSS 5.5. EPSS: 0.3% chance of exploitation in the next 30 days.

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.

Affected products

• Artem-Ogre Cdt: before 1.4.5 (fixed in 1.4.5)
