<p>cURL is a tool and libcurl is a library for transferring data with URL
|
||
syntax.

|
||
<description>
|
||
<p>cURL and applications linked against libcurl support “OCSP
|
||
stapling”, also known as the TLS Certificate Status Request extension
|
||
(using the CURLOPT_SSL_VERIFYSTATUS option). When telling cURL to use
|
||
this feature, it uses that TLS extension to ask for a fresh proof of the
|
||
server’s certificate’s validity. If the server doesn’t support the
|
||
extension, or fails to provide said proof, cURL is expected to return an
|
||
error.
|
||
Due to a coding mistake, the code that checks for a test success or
|
||
failure, ends up always thinking there’s valid proof, even when there
|
||
is none or if the server doesn’t support the TLS extension in question.
|
||

|
||
<impact type="normal">
|
||
<p>Due to the error, a user maybe does not detect when a server’s
|
||
certificate goes invalid or otherwise be mislead that the server is in a
|
||
better shape than it is in reality.
|
||
</p>

</impact>
|
||
<workaround>
|
||
<p>There is no known workaround at this time.</p>
|
||
</workaround>
|
||
<resolution>
|
||
<p>All cURL users should upgrade to the latest version:</p>

# emerge --ask --oneshot --verbose ">=net-misc/curl-7.53.0"
