NVD Description

Note: Versions mentioned in the description apply only to the upstream libcurl-debuginfo package and not the libcurl-debuginfo package as distributed by Centos. See How to fix? for Centos:10 relevant fixed versions and status.

Successfully using libcurl to do a transfer to a specific HTTP origin (hostA) with Digest authentication and then changing the origin to a different one (hostB) for a second transfer, reusing the same handle, makes libcurl wrongly pass on the Authorization: header field meant for hostA, to hostB.
