DESCRIPTION:
Tatsuya Kinoshita has reported a vulnerability in Lookup, which can
be exploited by malicious, local users to perform certain actions
with escalated privileges.
The vulnerability is caused due to temporary files being created
insecurely. This can be exploited via symlink attacks to overwrite
arbitrary files with the permissions of the user running the
application.
Successful exploitation requires that the "ndeb-binary" feature is
used.
SOLUTION:
Restrict access to trusted persons only. Do not use the "ndeb-binary"
feature.
