How to fix?

There is no fixed version for Centos:6 libcurl.

NVD Description

Note: Versions mentioned in the description apply only to the upstream libcurl package and not the libcurl package as distributed by Centos. See How to fix? for Centos:6 relevant fixed versions and status.

curl and libcurl before 7.50.1 do not check the client certificate when choosing the TLS connection to reuse, which might allow remote attackers to hijack the authentication of the connection by leveraging a previously created connection with a different client certificate.
