Name of the Vulnerable Software and Affected Versions
CGAL libcgal version 5.1.1
Description
A code execution vulnerability exists in the Nef polygon-parsing functionality. An out-of-bounds read vulnerability is present in the
SNC io parser::read sloop() function, specifically in Nef S2/SNC io parser.h, where slh->twin() is accessed. This can be triggered by an attacker providing malicious input, potentially allowing remote access to confidential data, disruption of data integrity, and denial of service.Recommendations
For CGAL libcgal version 5.1.1, consider disabling the
SNC io parser::read sloop() function until a patch is available to prevent exploitation. Restrict access to the Nef S2/SNC io parser.h module to minimize the risk of exploitation. Avoid using the slh->twin() variable in the affected API endpoint until the issue is resolved. At the moment, there is no information about a newer version that contains a fix for this vulnerability.Out of bounds Read
