Summary
A buffer overflow vulnerability in the DNS proxy and DNS Server features of Palo Alto Networks PAN-OS Software allows an unauthenticated attacker with network access to cause a denial of service (DoS) condition on all PAN-OS platforms except Cloud NGFW and Prisma Access, and potentially execute arbitrary code on PA-Series hardware by sending specially crafted network traffic.
Risk Assessment
The risk includes denial of service (DoS) on vulnerable PAN-OS platforms and, for PA-Series hardware, potential remote code execution, which could lead to device compromise and network security breach.
Recommendation
It is recommended to immediately apply security patches provided by Palo Alto Networks for affected PAN-OS versions and restrict network access to management interfaces and DNS services to trusted sources only.
