Wheezy missing DigiCert Root G2

[tom@tomputer.nl]

Hello,

I just noticed that my Debian Wheezy server is missing a few Digicert 
Root certificates:


Wheezy:
* DigiCert_Assured_ID_Root_CA.crt
* DigiCert_Global_Root_CA.crt
* DigiCert_High_Assurance_EV_Root_CA.crt

Jessie:
* DigiCert_Assured_ID_Root_CA.crt
* DigiCert_Assured_ID_Root_G2.crt
* DigiCert_Assured_ID_Root_G3.crt
* DigiCert_Global_Root_CA.crt
* DigiCert_Global_Root_G2.crt
* DigiCert_Global_Root_G3.crt
* DigiCert_High_Assurance_EV_Root_CA.crt
* DigiCert_Trusted_Root_G4.crt

I already tried to update the ca-certificates but it is already the 
latest version:

ca-certificates (20130119+deb7u1)

Is there a reason why these Digicert Root certificates are missing on 
Wheezy?

With kind regards,

Tom Wijnroks
