BlackBerry recently published an advisory warning of a privilege escalation vulnerability in the Z10 smartphone, which can be patched by upgrading to the latest version of the device's operating system (h/t Threatpost).

Still, the company noted, "Successful exploitation requires not only that a customer enable BlackBerry Protect, use the feature to reset the device password, and download a specifically crafted malicious app, but also that an attacker gain physical access to the smartphone. If all of the specific requirements are met for exploitation, an attacker could potentially access or modify data on the device."

Threatpost's Michael Mimoso notes that all users and administrators are advised to upgrade their devices to BlackBerry 10 OS version or later.
