CVE-2018-1079

pcs before version 0.9.164 and 0.10 is vulnerable to a privilege escalation
via authorized user malicious REST call. The REST interface of the pcsd
service did not properly sanitize the file name from the /remote/put_file
query. If the /etc/booth directory exists, an authenticated attacker with
write permissions could create or overwrite arbitrary files with arbitrary
data outside of the /etc/booth directory, in the context of the pcsd
process.
