Title: Multiple Ralinktech Wireless Drivers MAC/BSS/SSID Integer Overflow Vulnerability
Severity: CRITICAL
Description:
Ralink USB Wireless Adapter (RT73) is a wireless network adapter.
Multiple Ralinktech wireless drivers are prone to an integer-overflow vulnerability because they fail to ensure that integer values aren't overrun. Specifically, this issue occurs because the device's firmware fails to validate MAC, BSS, and SSID values.
An attacker can exploit this issue by sending a probe request packet with an SSID length larger than 128 bytes.
Successful exploits may allow remote attackers to execute arbitrary code with kernel-level privileges, resulting in the complete compromise of an affected device. Failed exploit attempts will likely cause denial-of-service conditions.
Ralink USB Wireless Adapter (RT73) 3.08 is affected. Other unspecified devices are also affected.
