Description
This security bulletin contains information about 1 vulnerability.
1) Integer overflow (CVE-ID: CVE-2017-12194)
CWE-ID: CWE-190 - Integer overflow
CVSSv4: CVSS:4.0/AV:A/AC:L/AT:N/PR:N/UI:A/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:P/U:Green
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.
