Critical

VectorAV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H
Name of the Vulnerable Software and Affected Versions CGAL libcgal version 5.1.1
Description The issue is related to multiple code execution vulnerabilities in the Nef polygon-parsing functionality. A specially crafted malformed file can lead to an out-of-bounds read and type confusion, potentially resulting in code execution. An attacker can provide malicious input to trigger these vulnerabilities. Specifically, an oob read vulnerability exists in the SNC io parser<EW>::read facet() function, which can be exploited by a remote attacker to access confidential data, compromise data integrity, and cause a denial of service using a specially crafted file.
Recommendations For CGAL libcgal version 5.1.1, consider disabling the SNC io parser<EW>::read facet() function to prevent exploitation until a patch is available. Restrict access to the Nef S2/SNC io parser.h component to minimize the risk of exploitation. Avoid using the fh->twin() function in the affected SNC io parser<EW>::read facet() function until the issue is resolved. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
