CVE-2025-15647

Name of the Vulnerable Software and Affected Versions CDT versions prior to 1.4.5

Description An out-of-bounds read occurs in the opposedVertexInd() function during the computation of constraint edge intersections in floating point when they round outside adjacent triangles. An attacker can trigger an out-of-bounds array access, leading to a process crash, by providing nearly-degenerate constraint edges through geometry data.

Recommendations Update to version 1.4.5 or later.
