In short
A flaw in CGAL's polygon parsing allows attackers to crash the application or potentially run malicious code by providing a specially crafted file. The vulnerability occurs when reading certain geometric data structures without proper boundary checking.
Technical detail
An out-of-bounds read vulnerability exists in CGAL 5.1.1's Nef polygon parser (SNC_io_parser.h) during sface boundary item processing, allowing type confusion and potential code execution. The attack vector requires providing a malformed input file; exploitation occurs during deserialization without bounds validation on array access.
Summary generated and translated by AI from the official description.
A code execution vulnerability exists in the Nef polygon-parsing functionality of CGAL libcgal CGAL-5.1.1. An oob read vulnerability exists in Nef_S2/SNC_io_parser.h SNC_io_parser<EW>::read_sface() store_sm_boundary_item() Edge_of.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.
