NVD Description

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

curl would wrongly reuse an existing HTTP proxy connection doing CONNECT to a server, even if the new request uses different credentials for the HTTP proxy. The proper behavior is to create or use a separate connection.
