Summary

Red Hat Security Advisory: openstack-nova secuity and bug fix advisory

Severity

Moderate

Notes

Topic: Updated OpenStack Compute packages that resolve one security issue and a bug are now available for Red Hat Enterprise Linux OpenStack Platform 5.0 for RHEL 7. Red Hat Product Security has rated this update as having Moderate security impact. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available from the CVE link in the References section.

Details: OpenStack Compute (nova) launches and schedules large networks of virtual machines, creating a redundant and scalable cloud computing platform. Compute provides the software, control panels, and APIs required to orchestrate a cloud, including running virtual machine instances and controlling access through users and projects. A vulnerability was discovered in the way OpenStack Compute (nova) networking handled security group updates; changes were not applied to already running VM instances. A remote attacker could use this flaw to access running VM instances. (CVE-2015-7713) Additional bug fixes include: * In some cases, Compute did not start instances when RHEL was installed with a locale other than en_US. The update ensures that logging an exception no longer causes Unicode issues. (BZ#1190837) All openstack-nova users are advised to upgrade to these updated packages, which correct these issues and add these enhancements.

CVE-2015-7713 (GCVE-0-2015-7713)

Vulnerability from cvelistv5 – Published: 2015-10-29 20:00 – Updated: 2024-08-06 07:58

Summary

OpenStack Compute (Nova) before 2014.2.4 (juno) and 2015.1.x before 2015.1.2 (kilo) do not properly apply security group changes, which allows remote attackers to bypass intended restriction by leveraging an instance that was running when the change was made.

Severity

No CVSS data available.

How durations are calculated

Following the VTEM framework (Black Hat USA 2015), time to patch starts when the vendor or a coordinator was informed, total time to patch at discovery, and disclosure to patch at public disclosure; vendor response time runs from the report to its acknowledgement. Time to exploit and time unpatched start at the earliest discovery or report, falling back to public disclosure. Unpatched time ends at the first recorded patch, or the calculation time when no patch is recorded. Exploitation to patch shows the interval between those two events; a published proof of concept is a public exploit, not exploitation.

Each result shows its source dates. A negative interval means the end event came first; when date-only inputs leave the order open, the result says so. Date-only inputs are approximate. The earliest evidence wins: KEV report dates and sightings are labelled as such. Records describing another vulnerability are listed but never calculated from, and a PoC alone does not establish exploitation. Missing patch evidence does not prove that no patch exists. Filters below change the event list only.
