OpenStack Compute (nova) 13.0.0 does not properly delete instances from compute nodes, which allows remote authenticated users to cause a denial of service (disk consumption) by deleting instances while in the resize state. NOTE: this vulnerability exists because of a CVE-2015-3280 regression.

A vulnerability was found in Openstack Glance. No limits are enforced within the Glance image service for both v1 and v2 `/images` API POST method for authenticated users, resulting in possible denial of service attacks through database table saturation.

In OpenStack Heat, by launching a new Heat stack with a local URL an authenticated user may conduct network discovery revealing internal network configuration. Affected versions are <=5.0.3, >=6.0.0 <=6.1.0, and ==7.0.0.

puppet-swift before versions 8.2.1, 9.4.4 is vulnerable to an information-disclosure in Red Hat OpenStack Platform director's installation of Object Storage (swift). During installation, the Puppet script responsible for deploying the service incorrectly removes and recreates the proxy-server.conf file with world-readable permissions.

puppet-tripleo before versions 5.5.0, 6.2.0 is vulnerable to an access-control flaw in the IPtables rules management, which allowed the creation of TCP/UDP rules with empty port values. If SSL is enabled, a malicious user could use these open ports to gain access to unauthorized resources.

glibc contains a vulnerability that allows specially crafted LD_LIBRARY_PATH values to manipulate the heap/stack, causing them to alias, potentially resulting in arbitrary code execution. Please note that additional hardening changes have been made to glibc to prevent manipulation of stack and heap memory but these issues are not directly exploitable, as such they have not been given a CVE. This affects glibc 2.25 and earlier.

Aodh as packaged in Openstack Ocata and Newton before change-ID I8fd11a7f9fe3c0ea5f9843a89686ac06713b7851 and before Pike-rc1 does not verify that trust IDs belong to the user when creating alarm action with the scheme trust+http, which allows remote authenticated users with knowledge of trust IDs where Aodh is the trustee to obtain a Keystone token and perform unspecified authenticated actions by adding an alarm action with the scheme trust+http, and providing a trust id where Aodh is the trustee.

A vulnerability was found in openstack-cinder releases up to and including Queens, allowing newly created volumes in certain storage volume configurations to contain previous data. It specifically affects ScaleIO volumes using thin volumes and zero padding. This could lead to leakage of sensitive information between tenants.

In OpenStack Nova through 14.0.9, 15.x through 15.0.7, and 16.x through 16.0.2, by rebuilding an instance, an authenticated user may be able to circumvent the Filter Scheduler bypassing imposed filters (for example, the ImagePropertiesFilter or the IsolatedHostsFilter). All setups using Nova Filter Scheduler are affected. Because of the regression described in Launchpad Bug #1732947, the preferred fix is a 14.x version after 14.0.10, a 15.x version after 15.0.8, or a 16.x version after 16.0.3.

An issue was discovered in middleware.py in OpenStack Swauth through 1.2.0 when used with OpenStack Swift through 2.15.1. The Swift object store and proxy server are saving (unhashed) tokens retrieved from the Swauth middleware authentication mechanism to a log file as part of a GET URI. This allows attackers to bypass authentication by inserting a token into an X-Auth-Token header of a new request. NOTE: github.com/openstack/swauth URLs do not mean that Swauth is maintained by an official OpenStack project team.

An issue was discovered in the default FilterScheduler in OpenStack Nova 16.0.3. By repeatedly rebuilding an instance with new images, an authenticated user may consume untracked resources on a hypervisor host leading to a denial of service, aka doubled resource allocations. This regression was introduced with the fix for OSSA-2017-005 (CVE-2017-16239); however, only Nova stable/pike or later deployments with that fix applied and relying on the default FilterScheduler are affected.

The tcpmss_mangle_packet function in net/netfilter/xt_TCPMSS.c in the Linux kernel before 4.11, and 4.9.x before 4.9.36, allows remote attackers to cause a denial of service (use-after-free and memory corruption) or possibly have unspecified other impact by leveraging the presence of xt_TCPMSS in an iptables action.

An issue was discovered in OpenStack Nova 15.x through 15.1.0 and 16.x through 16.1.1. By detaching and reattaching an encrypted volume, an attacker may access the underlying raw volume and corrupt the LUKS header, resulting in a denial of service attack on the compute host. (The same code error also results in data loss, but that is not a vulnerability because the user loses their own data.) All Nova setups supporting encrypted volumes are affected.

python-oslo-middleware before versions 3.8.1, 3.19.1, 3.23.1 is vulnerable to an information disclosure. Software using the CatchError class could include sensitive values in a traceback's error message. System users could exploit this flaw to obtain sensitive information from OpenStack component error logs (for example, keystone tokens).

An access-control flaw was found in the OpenStack Orchestration (heat) service before 8.0.0, 6.1.0 and 7.0.2 where a service log directory was improperly made world readable. A malicious system user could exploit this flaw to access sensitive information.

A flaw was found in openstack-tripleo-common as shipped with Red Hat Openstack Enterprise 10 and 11. The sudoers file as installed with OSP's openstack-tripleo-common package is much too permissive. It contains several lines for the mistral user that have wildcards that allow directory traversal with '..' and it grants full passwordless root access to the validations user.

OpenStack Nova-LXD before 13.1.1 uses the wrong name for the veth pairs when applying Neutron security group rules for instances, which allows remote attackers to bypass intended security restrictions.

An SSRF issue was discovered in OpenStack Glance before Newton. The 'copy_from' feature in the Image Service API v1 allowed an attacker to perform masked network port scans. With v1, it is possible to create images with a URL such as 'http://localhost:22'. This could then allow an attacker to enumerate internal network details while appearing masked, since the scan would appear to originate from the Glance Image service.

An issue was discovered in exception_wrapper.py in OpenStack Nova 13.x through 13.1.3, 14.x through 14.0.4, and 15.x through 15.0.1. Legacy notification exception contexts appearing in ERROR level logs may include sensitive information such as account passwords and authorization tokens.

OpenStack Horizon 9.x through 9.1.1, 10.x through 10.0.2, and 11.0.0 allows remote authenticated administrators to conduct XSS attacks via a crafted federation mapping.

A race-condition flaw was discovered in openstack-neutron before 7.2.0-12.1, 8.x before 8.3.0-11.1, 9.x before 9.3.1-2.1, and 10.x before 10.0.2-1.1, where, following a minor overcloud update, neutron security groups were disabled. Specifically, the following were reset to 0: net.bridge.bridge-nf-call-ip6tables and net.bridge.bridge-nf-call-iptables. The race was only triggered by an update, at which point an attacker could access exposed tenant VMs and network resources.

A flaw was found in instack-undercloud 7.2.0 as packaged in Red Hat OpenStack Platform Pike, 6.1.0 as packaged in Red Hat OpenStack Platform Oacta, 5.3.0 as packaged in Red Hat OpenStack Newton, 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.

In OpenStack Swift through 2.10.1, 2.11.0 through 2.13.0, and 2.14.0, the proxy-server logs full tempurl paths, potentially leaking reusable tempurl signatures to anyone with read access to these logs. All Swift deployments using the tempurl middleware are affected.

A vulnerability was found in openstack-tripleo-heat-templates before version 8.0.2-40. When deployed using Director using default configuration, Opendaylight in RHOSP13 is configured with easily guessable default credentials.

In the Federation component of OpenStack Keystone before 11.0.4, 12.0.0, and 13.0.0, an authenticated "GET /v3/OS-FEDERATION/projects" request may bypass intended access restrictions on listing projects. An authenticated user may discover projects they have no authority to access, leaking all projects in the deployment and their attributes. Only Keystone with the /v3/OS-FEDERATION endpoint enabled via policy.json is affected.

When using the Linux bridge ml2 driver, non-privileged tenants are able to create and attach ports without specifying an IP address, bypassing IP address validation. A potential denial of service could occur if an IP address, conflicting with existing guests or routers, is then assigned from outside of the allowed allocation pool. Versions of openstack-neutron before 13.0.0.0b2, 12.0.3 and 11.0.5 are vulnerable.
