openssh vulnerability clarification

Team,
             Below Advisory mentioned that openssh 7.9 is affected with few vulnerabilities  and on upgrade to 8.1.13 will resolve it.

but below pan os open source listing mentioned as openssh version is 6.4 is used.  So can you please confirm whether update is required and whether update to 8.1.13 will resolve the issue???

Or whether Openssh version identification method is incorrect??

 

Warm Regards,

Hi Team, Could you please help us here. !

@karthikeyanB @Sethupathi,

You'll probably get a better response for something this specific by opening a support case. My first thought would be that they aren't actually updating the OSS listings for each major release outside of initial release; so as the maintenance releases upgrade packages they aren't reflected in the OSS listing.

Hi @karthikeyanB , @Sethupathi , @BPry 

 

I would agree with BPry.

 

That said, you could just telnet to your device on port 22 and it should spit out the OpenSSH version it is using:

 

admin$ telnet 10.193.80.80 22
Trying 10.193.80.80...
Connected to 10.193.80.80.
Escape character is '^]'.
SSH-2.0-OpenSSH_12.1

 

Hope this helps,

I ended up having to do some research to find out why a vulnerability was flagging on a newer version of PAN-OS. 10.1 reports a correct version of SSH-2.0-OpenSSH_7.7 but an older PAN-OS of 8.1 reports an OpenSSH version that doesn't exist, the one you posted above, SSH-2.0-OpenSSH_12.1. This is not a valid OpenSSH version. The latest version 4 years later is 9.7. I can't find any resource online indicating why PAN would be misreporting the version.
