Scientific Linux Security Update : curl on SL7.x x86_64 (20161103)

high Nessus Plugin ID 95835
New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.

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.
