GCVE Workshop - 22 September 2026 (14:00-18:00), Luxembourg Before The Vulnopticon Conference - Registration

GSD-2020-35636

Vulnerability from gsd - Updated: 2023-12-13 01:22
Details
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() sfh->volume() 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.
