Version Summary:Red Hat and Mozilla have released security advisories and updated packages to address the Fraudulent French Directorate General of the Treasury Digital Certificates Spoofing Issue. CentOS has also released updated packages to address this issue.
 
 
Description
A fraudulently issued subordinate Certificate Authority (CA) certificate has been issued by the office of the Directorate General of the Treasury, a department of the French national government. The department is present in the Microsoft Windows Trusted Root Authorities Store. Attackers have used the fraudulently issued CA certificate to issue additional certificates for several third-party domains, including Google domains. Because the issuing CA certificate is trusted by Microsoft Windows systems, fraudulently issued certificates would also be trusted by Microsoft Windows systems.

By using the fraudulent certificates, an attacker could convince a user, web server, or other system that the attacker's identity matches that of a trusted third party. The attacker could abuse the certificate-based trust to conduct spoofing or phishing attacks in an attempt to gain information from a user. The attacker could also conduct man-in-the-middle attacks and monitor encrypted communications if a user trusts the fraudulent certificate and accesses remote servers using the certificate.

Microsoft has removed the fraudulent CA certificate from the trusted root, preventing Microsoft Windows systems from accepting the certificates as valid.
