RealNetworks RealPlayer MPG Width Integer Underflow Vulnerability - 91059

Hi Community,

 

A MPEG file trying to sync on One Drive but is being blocked by Palo Alto. 

 

Here is the signature RealNetworks RealPlayer MPG Width Integer Underflow Vulnerability - 91059 being the reason.  File is legit, what could be the reason of the block? The signature itself is based on an old CVE which has been resolved.

Hello,

Most likely there is a part of the file that is matching the vulnerability signature. You can open a TAC case to see if they will change the signature. Or you can create a new security policy with a special vulnerability policy that ignores this specific vulnerability.

Regards,
