Vulnerability from csaf_redhat - Published: 2017-09-06 16:53 - Updated: 2024-11-14 23:37Summary
Red Hat Security Advisory: instack-undercloud security, bug fix, and enhancement update
Notes
Topic
An update for instack-undercloud is now available for Red Hat OpenStack Platform 10.0 (Newton).
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.
Details
instack-undercloud provides a collection of scripts and elements that can be used to install an OpenStack undercloud (using python-instack).
The following packages have been upgraded to a later upstream version:
instack-undercloud (5.3.0). (BZ#1479841)
Security Fix(es):
* A flaw was found in instack-undercloud where pre-install and security
policy scripts used insecure temporary files. A local user could exploit
this flaw to conduct a symbolic-link attack, allowing them to overwrite the
contents of arbitrary files. (CVE-2017-7549)
This issue was discovered by Matthew Booth (Red Hat).
