The OpenSSL component of the Teradici PCoIP Software Client prior to version 21.07.0 was compiled without the no-autoload-config option, which allowed an attacker to elevate to the privileges of the running process via placing a specially crafted dll in a build configuration directory.

Affected Software

Name Vendor Start Version End Version
Pcoip_client Teradici * 21.07.0 (excluding)
