Description

An improper neutralization of special elements vulnerability in LXD&#39;s NVIDIA instance configuration handling allows an authenticated attacker to inject arbitrary configuration directives. By supplying newline characters within the &#39;nvidia.driver.capabilities&#39; or &#39;nvidia.require.*&#39; configuration values, an attacker can manipulate the generated lxc.conf file. This flaw enables the attacker to execute arbitrary code on the host system with the privileges of the LXD daemon.
