OVERVIEW

        Multiple vulnerabilities have been identified in Palo Alto Networks 
        PAN-OS. [1]


IMPACT

        The vendor has provided the following details regarding the issue:
        
        "Palo Alto Networks PAN-OS implements an API to enable programmatic
        device configuration and administration of the device. An issue was
        identified where the management API incorrectly parses input to a 
        specific API call, leading to execution of arbitrary OS commands 
        without authentication via the management interface. (Ref. #89717)"
        [1]
        
        "When a PAN-OS device is configured as a GlobalProtect web portal, a
        specially crafted request to the portal could result in a crash of 
        the service. (Ref. #89750)" [2]
        
        "When a PAN-OS device is configured as a GlobalProtect portal, a 
        vulnerability exists where an improper handling of a buffer involved
        in the processing of SSL VPN requests can result in device crash and
        possible remote code execution. (Ref. #89752)" [3]


MITIGATION

        The vendor recommends updating to version PAN-OS releases 
        5.0.18 and newer, 6.0.13 and newer, 6.1.10 and newer, 7.0.5H2 and 
        newer correct the issue. [1 - 3]
