CVSS v3.1
10
Critical
| 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 versions prior to 5.1.1
CGAL libcgal version 5.1.1
Description
The issue is related to unverified array indexing in the
SNC io parser<EW>::read vertex() function of the Nef S2/SNC io parser.h component in the CGAL library. This can be exploited by a remote attacker using a specially crafted file, potentially leading to unauthorized access to confidential data, data integrity violations, and denial of service. The vulnerability also involves out-of-bounds read and type confusion, which could result in code execution.Recommendations
For CGAL versions prior to 5.1.1, consider updating to a version that includes the fix for this issue.
For CGAL libcgal version 5.1.1, as a temporary workaround, consider restricting the use of the
SNC io parser<EW>::read vertex() function until a patch is available.
Avoid using the vh->sfaces begin() function in the affected SNC io parser<EW>::read vertex() function until the issue is resolved.Exploit
Fix
Improper Validation of Array Index
Out of bounds Read
