Description:
 A remote denial-of-service vulnerability exists in the way the Nouveau
 Display Driver (the default Ubuntu Nvidia display driver) handles GPU
 shader execution. A specially crafted pixel shader can cause remote
 denial-of-service issues. An attacker can provide a specially crafted
 website to trigger this vulnerability. This vulnerability can be triggered
 remotely after the user visits a malformed website. No further user
 interaction is required. Vulnerable versions include Ubuntu 18.04 LTS
 (linux 4.15.0-29-generic x86_64), Nouveau Display Driver NV117 (vermagic:
 4.15.0-29-generic SMP mod_unload).
