PAN-SA-2018-0015

Hi guys,

Just saw the notice about PAN-SA-2018-0015. Doesn't seem like this vulnerability is a real issue. Am I correct? Or is there a viable way of someone exploiting it?

In theory CVE-2018-0732 seems to be "easy" to use for a DoS attack against the firewall. I am not sure if openssl is used the same way as when the firewall initiates connections itself (updates, EDLs, ...), but if you disable DHE in the decryption profile you are probably safe. The other two aren't even medium criticality in my opinion. If I understood correctly for one you have to import a cert from an untrusted source and if someone is able to exploit 0739 then you have a much bigger problem than the possibility the attacker can regenerate a private key.

A customer recently upgraded to 8.0.14 to address this vulnerability. However after the upgrade, they noticed that 

SAML authentication for the Global Protect VPN client and the portal failed. The error in the log was 
and ( description contains 'Failure while validating the signature of SAML message received from the IdP "https://accounts.google.com/o/saml2?idpid=C00wscql4", because the certificate in the SAML Message doesn\'t match the IDP certificate configured on the IdP Server Profile "Google Apps IDP". (SP: "Global Protect"), (Client IP: 86.195.94.158), (vsys: vsys1), (authd id: 6627430890471424002)' )

When reverting to version 8.0.7, all works again. This would suggest a bug in 8.0.14. 

Is there a workaround for this vulnerability so that my customer doesn't have to worry about the SAML auth issue and remain on their current 8.0.7 code? Any suggestions much appreciated.
