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 CGAL-5.1.1
Description
The issue is related to the Nef polygon-parsing functionality in the CGAL library, specifically in the SNC io parser component. It involves unverified array indexing in the
read vertex() function, which can be exploited by a remote attacker using a specially crafted malformed file. This exploitation can lead to unauthorized access to confidential data, disruption of data integrity, and denial of service. The vulnerability also involves out-of-bounds read and type confusion, potentially leading to 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 CGAL-5.1.1, as a temporary workaround, consider restricting access to the
SNC io parser component until a patch is available.
Avoid using the read vertex() function in the affected SNC io parser component until the issue is resolved.Exploit
Fix
Out of bounds Read
Improper Validation of Array Index
