description

Windows 10 Version 1809 systems running the Xbox Live Networking Service are affected by a heap buffer overflow. An unauthenticated remote attacker may execute code when they can reach the vulnerable service over the network.

mitigation

Update affected Windows 10 Version 1809 systems to OS build 10.0.17763.9487 or later. Limit network exposure to the Xbox Live Networking Service until updates are deployed.

fixed in 10.0.17763.9487, 10.0.19044.7846, 10.0.19045.7846, 10.0.22631.7711, 10.0.26100.9974, 10.0.26200.9974, 10.0.28000.3501, 10.0.26300.9974
