Out-of-bounds Read in Cgal Computational Geometry Algorithms Library
CVE-2020-28615
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_vertex() vh->shalfedges_last().
EPSS: 0.023 (81.1th percentile) — read the EPSS interpretation.
