CRLF injection in the url_parse function in url.c
A CRLF injection flaw was found in the way wget handled URLs. A remote attacker could use this flaw to inject arbitrary HTTP headers in requests, via CRLF sequences in the host sub-component of a URL, by tricking a user running wget into processing crafted URLs. (CVE-2017-6508 )
Run yum update wget to update your system.
