Multiple BSD TCP/IP Stacks IP Fragmentation Remote DoS
Remote / Network Access Denial of Service
Loss of Availability
Exploit Public Vendor Verified

- 漏洞描述

Certain BSD derived TCP/IP stacks contain a flaw that may allow a remote denial of service. The issue is triggered when a malicious user creates and sends a pair of malformed IP packets that are reassembled into an invalid UDP datagram. The invalid UDP datagram will cause the kernel to panic and crash, resulting in a loss of availability for the platform.
