| 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 5.1.1
Description
The issue is related to the Nef polygon-parsing functionality in CGAL libcgal. A specially crafted malformed file can lead to an out-of-bounds read and type confusion, potentially resulting in code execution. The vulnerability is also associated with unchecked array indexing in the
PM io parser<PMDEC>::read hedge() function, specifically in the e->set vertex() call. This could allow a remote attacker to access confidential data, compromise data integrity, and cause a denial of service using a specially crafted file. The PM io parser<PMDEC>::read hedge() function in the Nef 2/PM io parser.h component of the CGAL library is affected.Recommendations
For CGAL libcgal version 5.1.1, consider disabling the
PM io parser<PMDEC>::read hedge() function until a patch is available to prevent potential code execution and data integrity issues. Restrict access to the Nef 2/PM io parser.h component to minimize the risk of exploitation. Avoid using the e->set vertex() call in the affected PM io parser<PMDEC>::read hedge() function until the issue is resolved. At the moment, there is no information about a newer version that contains a fix for this vulnerability.Exploit
Improper Validation of Array Index
Out of bounds Read
