|Title:||PZOS CIFS Buffer Overflow|
|Affected Products:||PZOS 22.214.171.124.5075.E or Below|
A vulnerability in the CIFS implementation on the Panzura PZOS version 126.96.36.199.5075.E or below has been discovered. This vulnerability may result in an unauthorized user executing arbitrary code via a structured request.
A buffer overflow condition can exist in the PZOS implementation of the CIFS protocol whereby a specifically constructed mount request could disable the Cloud Controller CIFS service to the client base and potentially execute arbitrary code via an exposed file share.
An exploit (none known to exist at this time) of this vulnerability could result in unauthorized access or data modification, disruption of service, or disabling the appliance.
Upgrade the Panzura software to PZOS version 188.8.131.52 or higher; any future major or minor releases will also correct the issue. Release notes for this version will outline details as necessary for this correction.
