CVE-2020-28604
Multiple code execution vulnerabilities exists in the Nef polygon-parsing functionality of CGAL libcgal CGAL-5.1.1.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (2.30%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
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_2/PM_io_parser.h PM_io_parser<PMDEC>::read_hedge() e->set_next().
