  "details" : [ "When doing TLS related transfers with reused easy or multi handles and\naltering the  `CURLSSLOPT_NO_PARTIALCHAIN` option, libcurl could accidentally\nreuse a CA store cached in memory for which the partial chain option was\nreversed. Contrary to the user's wishes and expectations. This could make\nlibcurl find and accept a trust chain that it otherwise would not.", "A flaw was found in libcurl. When handling secure connections (TLS) and reusing connection settings, libcurl could incorrectly apply a cached security setting related to certificate chain validation. This could allow libcurl to accept a server's security certificate that it should have otherwise rejected, potentially compromising the integrity of the secure connection." ],
  "statement" : "This vulnerability is rated Low for Red Hat. `libcurl` could incorrectly reuse a cached CA store when applications alter the `CURLSSLOPT_NO_PARTIALCHAIN` option with re-used easy or multi handles. This could lead to the acceptance of an otherwise untrusted TLS trust chain. Exploitation requires specific application logic that dynamically changes this option while reusing `libcurl` handles.",
