Details

When doing TLS related transfers with reused easy or multi handles and altering the CURLSSLOPT_NO_PARTIALCHAIN option, libcurl could accidentally reuse a CA store cached in memory for which the partial chain option was reversed. Contrary to the user's wishes and expectations. This could make libcurl find and accept a trust chain that it otherwise would not.
