Samba Out-of-Bounds Heap R/W Remote Code Execution (RCE) Vulnerability (CVE-2021-44142)

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,

@paragkarki143,

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.
