Описание
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.
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.
Отчет
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.
