| Vector | AV: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 CGAL-5.1.1
Description
The issue is related to an error in parsing Nef polygons in the PM io parser::read vertex() function of the CGAL library. This can allow a remote attacker to access confidential data, compromise its integrity, and cause a denial of service. The vulnerability exists in the Nef polygon-parsing functionality and is triggered by an out-of-bounds read in the PM io parser::read vertex() function. An attacker can exploit this by providing malicious input.
Recommendations
For CGAL libcgal version CGAL-5.1.1, consider disabling the
PM io parser::read vertex() function until a patch is available to prevent exploitation. Restrict access to the Nef 2/PM io parser.h module to minimize the risk of exploitation. Avoid using the Face of[] array 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
