Description
A Denial of Service (DoS) vulnerability in Palo Alto Networks PAN-OS software causes the firewall to unexpectedly reboot when processing a specially crafted LLDP frame sent by an unauthenticated adjacent attacker. Repeated attempts to initiate this condition causes the firewall to enter maintenance mode. This issue does not apply to Cloud NGFWs or Prisma Access software.

Workaround: Option 1: If you are not using LLDP, you should disable it to mitigate this issue by performing the following steps in your web interface: * Select Network > LLDP. * Open LLDP General settings. * Disable (uncheck) LLDP. Option 2: You can disable LLDP for your network interfaces by performing the following steps in your web interface: * Select Network > Interfaces and select the interface you wish to disable LLDP for. * Select Advanced > LLDP. * Disable (uncheck) LLDP. Option 3: If you are using LLDP only to advertise information about your PAN-OS device to other neighboring devices, you should set the LLDP mode to transmit-only for the profile used on your network interfaces by performing the following steps in your web interface: * Select Network > Network Profiles > LLDP Profile * Select the profile used with the interface * Set the "Mode" to "transmit-only".
