A vulnerability was reported in Microsoft Windows. A remote user may be able to spoof SSL certificates.

 

The operating system includes an invalid subordinate certificate issued by Directorate General of the Treasury (DG Tresor), subordinate to the Government of France CA (ANSSI).

 

The invalid certificate and its thumbprint is: AC DG Tresor SSL: 5c e3 39 46 5f 41 a1 e4 23 14 9f 65 54 40 95 40 4d e6 eb e2
