Descriptions

A code execution vulnerability exists in the Nef polygon-parsing functionality of CGAL libcgal CGAL-5.1.1 in Nef_S2/SNC_io_parser.h SNC_io_parser::read_sface() sfh->volume() OOB read. A specially crafted malformed file can lead to an out-of-bounds read and type confusion, which could lead to code execution. An attacker can provide malicious input to trigger this vulnerability.

Se presenta una vulnerabilidad de ejecución de código en la funcionalidad polygon-parsing de Nef de CGAL libcgal versión CGAL-5.1.1 en Nef_S2/SNC_io_parser.h SNC_io_parser::read_sface() sfh->volume() OOB read. Un archivo con formato incorrecto especialmente diseñado puede provocar una lectura fuera de límites y confusión de tipos, lo que podría conducir a la ejecución del código. Un atacante puede proporcionar información malintencionada para desencadenar esta vulnerabilidad.
