CVE-2020-28611: Out-of-bounds Read
First published: Mon Apr 18 2022(Updated: )
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/SM_io_parser.h SM_io_parser<Decorator_>::read_vertex() set_first_out_edge().
