Scientific Linux Security Update : curl on SL7.x x86_64

This script is Copyright (C) 2016 Tenable Network Security, Inc.


Synopsis :

The remote Scientific Linux host is missing one or more security
updates.

Description :

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.
