How to fix?

There is no fixed version for RHEL:7 libcurl.

NVD Description

Note: Versions mentioned in the description apply only to the upstream libcurl package and not the libcurl package as distributed by RHEL. See How to fix? for RHEL:7 relevant fixed versions and status.

The libcurl API function called curl_maprintf() before version 7.51.0 can be tricked into doing a double-free due to an unsafe size_t multiplication, on systems using 32 bit size_t variables.
