Early Access — Mondoo Vulnerability Intelligence is currently in preview.
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.
