Intel WIFI Drivers and PROSet/Wireless WiFi Software Multiple Memory Corruption Vulnerabilities



Date Discovered

November 12, 2019


Intel WIFI Drivers and PROSet/Wireless WiFi Software are prone to multiple memory-corruption vulnerabilities. A local attacker can leverage these issues to gain elevated privileges, gain sensitive information and cause denial-of-service conditions. Intel WIFI Drivers and PROSet/Wireless WiFi Software versions prior to 21.40 are vulnerable.

Permit local access for trusted individuals only. Where possible, use restricted environments and restricted shells.
Allow only trusted and accountable individuals to have local interactive access to the vulnerable computer.

Block external access at the network boundary, unless external parties require service.
If global access isn't needed, filter access to the affected computer at the network boundary. Restricting access to only trusted computers and networks might greatly reduce the likelihood of successful exploits.

Run all software as a nonprivileged user with minimal access rights.
To reduce the impact of latent vulnerabilities, run all applications with the minimal amount of privileges required for functionality.

Do not accept or execute files from untrusted or unknown sources.
To reduce the likelihood of successful exploits, never handle files that originate from unfamiliar or untrusted sources.

Implement multiple redundant layers of security.
Since some of these issues may be leveraged to execute code, we recommend memory-protection schemes, such as nonexecutable stack/heap configurations and randomly mapped memory segments. This tactic may complicate exploits of memory-corruption vulnerabilities.

Evaluate read, write, and execute permissions on all newly installed software.
To limit exposure to these and other latent vulnerabilities, evaluate setgid and setuid settings on all installed applications.

Updates are available. Please see the references or vendor advisory for more information.
