What is CVE-2018-5764?

The parse_arguments function in rsyncd before version 3.1.3 has a weakness where it does not restrict multiple uses of the --protect-args flag. This vulnerability can be exploited by remote attackers to circumvent the argument-sanitization mechanism, potentially allowing them to execute commands or gain unauthorized access to system resources.
