Problem Description:
The 802.11 beacon handling routine failed to validate the length of
an IEEE 802.11s Mesh ID before copying it to a heap-allocated
buffer.
Impact:
While a FreeBSD Wi-Fi client is in scanning mode (i.e., not
associated with a SSID) a malicious beacon frame may overwrite kernel
memory, leading to remote code execution.
