CVE-2025-15647

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.

Summary		(es) CDT anterior a la 1.4.5 contiene una vulnerabilidad de lectura fuera de límites en la función opposedVertexInd() cuando las intersecciones de los bordes de restricción se calculan en coma flotante y se redondean fuera de los triángulos adyacentes. Los atacantes pueden proporcionar bordes de restricción casi degenerados a través de datos de geometría para desencadenar un acceso a un array fuera de límites que provoca el bloqueo del proceso de llamada.
