Description
A stack-based buffer overflow vulnerability in the log processing functionality of Palo Alto Networks PAN-OS® software on Panorama enables an attacker to cause a denial of service (DoS) condition. Repeated attempts to trigger this condition result in the Panorama entering maintenance mode. Cloud NGFW, Prisma® Access, and standalone PAN-OS firewalls are not affected by this vulnerability.
