How to fix?

There is no fixed version for RHEL: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 RHEL. See How to fix? for RHEL:6 relevant fixed versions and status.

Successfully using libcurl to do a transfer over a specific HTTP proxy (proxyA) with Digest authentication and then changing the proxy host to a second one (proxyB) for a second transfer, reusing the same handle, makes libcurl wrongly pass on the Proxy-Authorization: header field meant for proxyA, to proxyB.
