CVE-2016-5419 (opens in a new tab)How to fix?
Upgrade RHEL:7 curl to version 0:7.29.0-35.el7 or higher.
This issue was patched in RHSA-2016:2575.
NVD Description
Note: Versions mentioned in the description apply only to the upstream curl package and not the curl package as distributed by RHEL.
See How to fix? for RHEL:7 relevant fixed versions and status.
curl and libcurl before 7.50.1 do not prevent TLS session resumption when the client certificate has changed, which allows remote attackers to bypass intended restrictions by resuming a session.
