Description

This security bulletin contains information about 1 security vulnerability.


1) Integer overflow (CVE-ID: CVE-2017-12194)

The vulnerability allows an adjacent unauthenticated attacker to gain elevated privileges on the target system.

The weakness exists in the spice-gtk component due to improper sanitization of pointers and lengths when handling spice-server messages. An adjacent attacker can trick the victim into connecting to an attacker-controlled spice-server and send messages that submit malicious input, trigger integer overflow and execute arbitrary code with root privileges.
