Vulnerability from csaf_redhat - Published: 2014-01-22 18:31 - Updated: 2026-07-31 11:41Summary
Red Hat Security Advisory: openstack-neutron security, bug fix, and enhancement update
Severity
Moderate
Notes
Topic: Updated openstack-neutron packages that fix one security issue, several
bugs, and add various enhancements are now available for Red Hat Enterprise
Linux OpenStack Platform 4.0.
The Red Hat Security Response Team 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: The openstack-neutron packages provide Openstack Networking (neutron), the
virtual network service.
It was discovered that the metadata agent in OpenStack Networking was
missing an authorization check on the device ID that is bound to a specific
port. A remote tenant could guess the instance ID bound to a port and
retrieve metadata of another tenant, resulting in information disclosure.
Note that only OpenStack Networking setups running neutron-metadata-agent
were affected. (CVE-2013-6419)
Red Hat would like to thank Jeremy Stanley of the OpenStack Project for
reporting this issue. Upstream acknowledges Aaron Rosen of VMware as the
original reporter.
The openstack-neutron packages have been upgraded to upstream version
2013.2.1, which provides a number of bug fixes and enhancements over the
previous version. The most notable fixes and enhancements are:
- Support for multiple workers in the Neutron API. This can be achieved by
setting the 'workers=' parameter in the neutron.conf file.
- The downtime and report interval default settings are tuned for
neutron agents.
- The floating IP address stability has been enhanced.
- A heartbeat-related deadlock problem in neutron-server has been fixed.
(BZ#1045419)
This update also fixes the following bugs:
* An incorrect warning was displayed when running neutron-dhcp-agent with
Red Hat Enterprise Linux's version of dnsmasq. This meant that users were
incorrectly warned that Red Hat Enterprise Linux's dnsmasq version will not
work with neutron-dhcp-agent. This warning has been removed, and will no
longer be logged to the neutron-dhcp-agent log file. (BZ#1040196)
* A bug in the QPID topic consumer re-connection logic (under the v2
topology) caused qpidd to use a malformed subscriber address after
restarting, resulting in RPC requests sent to a topic with multiple servers
ending up being incorrectly multicast to all servers. This update removes
the special-case reconnect logic that handles UUID addresses, which in turn
avoids the incorrect establishment of multiple subscription to the same
fanout address. The QPID broker now simply automatically generates unique
queue names when clients reconnect. (BZ#1045067)
* Thread-consuming QPID messages were killed silently by unhandled errors,
thus resulting in isolating the component from the rest of the system.
With this update, consuming threads are made more resilient to errors by
ensuring they do not die on an unhandled error. The error is now logged,
and the consuming thread is retried. (BZ#1054249)
In addition, this update adds the following enhancement:
* Previously, instances connected to tenant networks gained outside
connectivity by going through an SNAT by the L3 agent hosting that
network's virtual router. With this release, the ability to disable
SNAT/PAT on virtual servers is added ensuring that an instance in a tenant
network subnet will retain its IP address as it passes through external
networks. For example, if 10.0.0.1 is an instance in the 10.0.0.0/8 tenant
network, R1, a virtual router that connects the 10.0.0.0/8 subnet to the
20.0.0.0/8 public provider networks, then you can use the 'neutron
router-gateway-set --disable-snat R1 public' command and any traffic from
10.0.0.1, which is forwarded out to the provider network, will retain its
actual source IP address of 10.0.0.1. This can be a flexible and useful
method to connect instances directly to a provider network, while retaining
it in a tenant network. (BZ#1046070)
All openstack-neutron users are advised to upgrade to these updated
packages, which correct these issues and add these enhancements.

Interaction error in OpenStack Nova and Neutron before Havana 2013.2.1 and icehouse-1 does not validate the instance ID of the tenant making a request, which allows remote tenants to obtain sensitive metadata by spoofing the device ID that is bound to a port, which is not properly handled by (1) api/metadata/handler.py in Nova and (2) the neutron-metadata-agent (agent/metadata/agent.py) in Neutron.

Drag nodes to arrange them. Double-click a related vulnerability to open it, or a source to visit its link. The Physics button on the left tunes the layout and the simulation; the legend at the bottom left hides or shows nodes by kind and by sighting type.
Experimental. This forecast is provided for visualization only and may change without notice. Do not use it for operational decisions.
Forecast uses a logistic model when the trend is rising, or an exponential decay model when the trend is falling. Fitted via linearized least squares.

Nomenclature
- Seen: The vulnerability was mentioned, discussed, or observed by the user.
- Confirmed: The vulnerability has been validated from an analyst's perspective.
- Published Proof of Concept: A public proof of concept is available for this vulnerability.
- Exploited: The vulnerability was observed as exploited by the user who reported the sighting.
- Patched: The vulnerability was observed as successfully patched by the user who reported the sighting.
- Not exploited: The vulnerability was not observed as exploited by the user who reported the sighting.
- Not confirmed: The user expressed doubt about the validity of the vulnerability.
- Not patched: The vulnerability was not observed as successfully patched by the user who reported the sighting.
Vulnerability timeline
Sightings and recorded dates, grouped by day · UTC
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.

model, served locally by ML-Gateway.
They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
