  "details": "libcurl might in some circumstances reuse the wrong connection when asked to do Negotiate-authenticated ones, even when they are set to use different \"services\".  libcurl features a pool of recent connections so that subsequent requests can reuse an existing connection to avoid overhead.  When reusing a connection a range of criteria must be met. Due to a logical error in the code, a request that was issued by an application could wrongfully reuse an existing connection to the same server that was authenticated using different services.",
