Hi All,
I would like to know if PAN-OS is affected by the Samba Out-of-Bounds Heap R/W Remote Code Execution (RCE) Vulnerability (CVE-2021-44142) and if they are what actions need to be taken.
We are running 9.1.11-h3 on PA-Firewall and 8.1.15 Panorama.
I have searched the PA threat vault and cannot find anything related there.
Many Thanks,

First and foremost, your Panorama major version should never be behind your firewalls. I'd recommend upgrading your Panorama instance to 9.1 at least to match your firewalls.
While PAN-OS uses Samba, Panorama does not. Since PAN-OS only uses Samba internally and it isn't exposed, I don't believe this would be exploitable at all in its current deployment.

@BPry Do you have any idea on this? Thank you in advance.
