DESCRIPTION:
A security issue has been reported in v86d, which can be exploited by
malicious, local users to bypass certain security restrictions.
The security issue is caused due to v86d not properly verifying the
origin of Netlink messages, which can be exploited to e.g. manipulate
certain uvesafb settings by sending Netlink messages to v86d.
The security issue is reported in versions prior to 0.1.10.
SOLUTION:
Update to version 0.1.10.
