Issue Date: 2016-11-03
CVE Numbers: CVE-2016-5419
CVE-2016-5420
CVE-2016-7141

Security Fix(es):
* It was found that the libcurl library did not prevent TLS session
resumption when the client certificate had changed. An attacker could
potentially use this flaw to hijack the authentication of the connection
by leveraging a previously created connection with a different client
certificate. (CVE-2016-5419)
* It was found that the libcurl library did not check the client
certificate when choosing the TLS connection to reuse. An attacker could
potentially use this flaw to hijack the authentication of the connection
by leveraging a previously created connection with a different client
certificate. (CVE-2016-5420)
* It was found that the libcurl library using the NSS (Network Security
Services) library as TLS/SSL backend incorrectly re-used client
certificates for subsequent TLS connections in certain cases. An attacker
could potentially use this flaw to hijack the authentication of the
connection by leveraging a previously created connection with a different
client certificate. (CVE-2016-7141)
