EulerOS 2.0 SP1 : curl (EulerOS-SA-2016-1074)

This script is Copyright (C) 2017 Tenable Network Security, Inc.


Synopsis :

The remote EulerOS host is missing multiple security updates.

Description :

According to the versions of the curl packages installed, the EulerOS
installation on the remote host is affected by the following
vulnerabilities :

- 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)

Note that Tenable Network Security has extracted the preceding
description block directly from the EulerOS security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues.
