Red Hat Security Advisory 2016-2575-02
Posted Nov 3, 2016
Authored by Red Hat | Site access.redhat.com

Red Hat Security Advisory 2016-2575-02 - The curl packages provide the libcurl library and the curl utility for downloading files from servers using various protocols, including HTTP, FTP, and LDAP. Security Fix: 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.

Red Hat Security Advisory

Synopsis: Moderate: curl security, bug fix, and enhancement update
Advisory ID: RHSA-2016:2575-02
Product: Red Hat Enterprise Linux
Advisory URL: https://rhn.redhat.com/errata/RHSA-2016-2575.html
Issue date: 2016-11-03
CVE Names: CVE-2016-5419 CVE-2016-5420 CVE-2016-7141
=====================================================================

1. Summary:

An update for curl is now available for Red Hat Enterprise Linux 7.

Red Hat Product Security has rated this update as having a security impact
of Moderate. A Common Vulnerability Scoring System (CVSS) base score, which
gives a detailed severity rating, is available for each vulnerability from
the CVE link(s) in the References section.

2. Relevant releases/architectures:

Red Hat Enterprise Linux Client (v. 7) - x86_64
Red Hat Enterprise Linux Client Optional (v. 7) - x86_64
Red Hat Enterprise Linux ComputeNode (v. 7) - x86_64
Red Hat Enterprise Linux ComputeNode Optional (v. 7) - x86_64
Red Hat Enterprise Linux Server (v. 7) - aarch64, ppc64, ppc64le, s390x, x86_64
Red Hat Enterprise Linux Workstation (v. 7) - x86_64

3. Description:

The curl packages provide the libcurl library and the curl utility for
downloading files from servers using various protocols, including HTTP,
FTP, and LDAP.

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)

Additional Changes:

For detailed information on changes in this release, see the Red Hat
Enterprise Linux 7.3 Release Notes linked from the References section.
