CVE-2019-11236
Description
From CVE.org
In the urllib3 library through 1.24.1 for Python, CRLF injection is possible if the attacker controls the request parameter.
Statement
This issue affects the version of python-urllib3 shipped with Red Hat Gluster Storage 3, as it is vulnerable to CRLF injection.
Red Hat Satellite 6.2 is on Maintenance Support 2 phase, hence only selected critical and important issues will be fixed. Please refer to Red Hat Satellite Product Life Cycle page for more information.
In Red Hat OpenStack Platform 13, because the flaw has a lower impact and the fix would require a substantial amount of development, no update will be provided at this time for the RHOSP python-urllib3 package.
Common Vulnerability Scoring System (CVSS) Score Details
Info alert:Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).
