CVE-2017-7189 (opens in a new tab)How to fix?
There is no fixed version for Centos:8 php-bcmath.
NVD Description
Note: Versions mentioned in the description apply only to the upstream php-bcmath package and not the php-bcmath package as distributed by Centos.
See How to fix? for Centos:8 relevant fixed versions and status.
main/streams/xp_socket.c in PHP 7.x before 2017-03-07 misparses fsockopen calls, such as by interpreting fsockopen('127.0.0.1:80', 443) as if the address/port were 127.0.0.1:80:443, which is later truncated to 127.0.0.1:80. This behavior has a security risk if the explicitly provided port number (i.e., 443 in this example) is hardcoded into an application as a security policy, but the hostname argument (i.e., 127.0.0.1:80 in this example) is obtained from untrusted input.
