Description
The Broadcom wl WiFi driver is vulnerable to a heap buffer overflow. If the vendor information element data length is larger than 164 bytes, a heap buffer overflow is triggered in wlc_wpa_plumb_gtk. In the worst case scenario, by sending specially-crafted WiFi packets, a remote, unauthenticated attacker may be able to execute arbitrary code on a vulnerable system. More typically, this vulnerability will result in denial-of-service conditions.
