Descriptions

Multiple code execution vulnerabilities exists in the Nef polygon-parsing functionality of CGAL libcgal CGAL-5.1.1. 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 any of these vulnerabilities. An oob read vulnerability exists in Nef_S2/SNC_io_parser.h SNC_io_parser<EW>::read_facet() fh->boundary_entry_objects SEdge_of.

Se presentan múltiples vulnerabilidades de ejecución de código en la funcionalidad de análisis de polígonos Nef de CGAL libcgal versión CGAL-5.1.1. Un archivo malformado especialmente diseñado puede conllevar a una lectura fuera de límites y una confusión de tipo, lo que podría conllevar a una ejecución de código. Un atacante puede proporcionar una entrada maliciosa para desencadenar cualquiera de estas vulnerabilidades. Se presenta una vulnerabilidad de lectura fuera de límites en el archivo Nef_S2/SNC_io_parser.h en la función SNC_io_parser(EW)::read_facet() fh-)boundary_entry_objects SEdge_of
