+ <background>
+ <p>cURL is a tool and libcurl is a library for transferring data with URL
+ syntax.
+ </p>
+ </background>
+ <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.
+ </p>
+ </description>
+ <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>
+
+ <code>
+ # emerge --sync
+ # emerge --ask --oneshot --verbose "&gt;=net-misc/curl-7.53.0"
+ </code>
