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.

A flaw was found in curl before version 7.51.0 When re-using a connection, curl was doing case insensitive comparisons of user name and password with the existing connections. This means that if an unused connection with proper credentials exists for a protocol that has connection-scoped credentials, an attacker can cause that connection to be reused if s/he knows the case-insensitive version of the correct password.
