NVD Description

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

curl before version 7.52.0 is vulnerable to a buffer overflow when doing a large floating point output in libcurl's implementation of the printf() functions. If there are any application that accepts a format string from the outside without necessary input filtering, it could allow remote attacks.
