Synopsis

A VPN client installed on remote Windows host is affected by a denial-of-service (DoS) vulnerability.

Description

The version of Palo Alto GlobalProtect Agent installed on the remote Windows host is 5.1.x prior to 5.1.8, or 5.2.x prior to 5.2.4. It is, therefore, affected by a denial-of-service (DoS) vulnerability. A denial-of-service (DoS) vulnerability in Palo Alto Networks GlobalProtect app on Windows systems allows a limited Windows user to send specifically-crafted input to the GlobalProtect app that results in a Windows blue screen of death (BSOD) error.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Upgrade to Palo Alto GlobalProtect Agent 5.1.8, 5.2.4 or later
