CVE-2020-35635
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() store_sm_boundary_item() Sloop_of OOB read.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (2.38%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
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() store_sm_boundary_item() Sloop_of 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.
