A design flaw issue was found in the Red Hat OpenStack Platform director use of TripleO to enable libvirtd based live-migration. Libvirtd is deployed by default (by director) listening on 0.0.0.0 (all interfaces) with no-authentication or encryption. Anyone able to make a TCP connection to any compute host IP address, including 127.0.0.1, other loopback interface addresses, or in some cases possibly addresses that have been exposed beyond the management interface, could use this to open a virsh session to the libvirtd instance and gain control of virtual machine instances or possibly take over the host.

A heap buffer overflow flaw was found in QEMU's Cirrus CLGD 54xx VGA emulator's VNC display driver support before 2.9; the issue could occur when a VNC client attempted to update its display after a VGA operation is performed by a guest. A privileged user/process inside a guest could use this flaw to crash the QEMU process or, potentially, execute arbitrary code on the host with privileges of the QEMU process.

The OpenStack RabbitMQ container image insecurely retrieves the rabbitmqclusterer component over HTTP during the build stage. This could potentially allow an attacker to serve malicious code to the image builder and install in the resultant container image. Version of openstack-rabbitmq-container and openstack-containers as shipped with Red Hat Openstack 12, 13, 14 are believed to be vulnerable.

CVE-2008-4796 describes a command execution flaw in the Snoopy library. A similar fix exists for headers:

http://snoopy.cvs.sourceforge.net/viewvc/snoopy/Snoopy/Snoopy.class.php?view=log#rev1.27

The header fix has been assigned CVE-2008-7313 (as an incomplete fix for CVE-2008-4796).

It was later reported that the CVE-2008-4796 fix was incomplete and command execution was still possible:

http://mstrokin.com/sec/feed2js-magpierss-0day-vulnerability-not-really-it-is-actually-cve-2005-3330-cve-2008-4796/

And fixed with the following:

http://snoopy.cvs.sourceforge.net/viewvc/snoopy/Snoopy/Snoopy.class.php?view=log#rev1.28

This has been assigned CVE-2014-5008 (as an incomplete fix for CVE-2008-4796).

However, the CVE-2014-5008 fix was also incomplete:

https://github.com/cogdog/feed2js/pull/12#issuecomment-48283706

This was fixed with the following:

http://snoopy.cvs.sourceforge.net/viewvc/snoopy/Snoopy/Snoopy.class.php?view=log#rev1.29

And assigned CVE-2014-5009 (as an incomplete fix for CVE-2014-5008).

Snoopy allows remote attackers to execute arbitrary commands. NOTE: this vulnerability exists due to an incomplete fix for CVE-2014-5008.

Snoopy allows remote attackers to execute arbitrary commands.

The C+ mode offload emulation in the RTL8139 network card device model in QEMU, as used in Xen 4.5.x and earlier, allows remote attackers to read process heap memory via unspecified vectors.

A vulnerability was found in openstack-ironic-inspector all versions excluding 5.0.2, 6.0.3, 7.2.4, 8.0.3 and 8.2.1. A SQL-injection vulnerability was found in openstack-ironic-inspector's nodecache.findnode(). This function makes a SQL query using unfiltered data from a server reporting inspection results (by a POST to the /v1/continue endpoint). Because the API is unauthenticated, the flaw could be exploited by an attacker with access to the network on which ironic-inspector is listening. Because of how ironic-inspector uses the query results, it is unlikely that data could be obtained. However, the attacker could pass malicious data and create a denial of service.

Buffer overflow in the pcnetreceive function in hw/net/pcnet.c in QEMU, when a guest NIC has a larger MTU, allows remote attackers to cause a denial of service (guest OS crash) or execute arbitrary code via a large packet.

Qemu emulator built with VGA emulation with VESA BIOS Extensions(VBE) support is vulnerable to an OOB r/w access issue. It could occur while doing VGA r/w operations via i/o port methods.

A privileged guest user could use this flaw to potentially execute arbitrary code, with privileges of the Qemu process on the host.

The image build process for the overcloud images in Red Hat OpenStack Platform 8.0 (Liberty) director and Red Hat Enterprise Linux OpenStack Platform 7.0 (Kilo) director (aka overcloud-full) use a default root password of ROOTPW, which allows attackers to gain access via unspecified vectors.

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.

The netchecksumcalculate function in net/checksum.c in QEMU allows local guest OS users to cause a denial of service (out-of-bounds heap read and crash) via the payload length in a crafted packet.

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.

Memory leak in the audio/audio.c in QEMU (aka Quick Emulator) allows remote attackers to cause a denial of service (memory consumption) by repeatedly starting and stopping audio capture.

Heap-based buffer overflow in Cirrus CLGD 54xx VGA Emulator in Quick Emulator (Qemu) 2.8 and earlier allows local guest OS users to execute arbitrary code or cause a denial of service (crash) via vectors related to a VNC client updating its display after a VGA operation.

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.

Heap-based buffer overflow in the iscsiaioioctl function in block/iscsi.c in QEMU allows local guest OS users to cause a denial of service (QEMU process crash) or possibly execute arbitrary code via a crafted iSCSI asynchronous I/O ioctl call.

A vulnerability was found in ceilometer before version 12.0.0.0rc1. An Information Exposure in ceilometer-agent prints sensitive configuration data to log files without DEBUG logging being activated.

app/controllers/api/v1/hostscontroller.rb in Foreman before 1.2.2 does not properly restrict access to hosts, which allows remote attackers to access arbitrary hosts via an API request.

Multiple SQL injection vulnerabilities in app/models/concerns/hostcommon.rb in Foreman before 1.2.3 allow remote attackers to execute arbitrary SQL commands via the (1) fqdn or (2) hostgroup parameter.

Smart Proxy (aka Smart-Proxy and foreman-proxy) in Foreman before 1.5.4 and 1.6.x before 1.6.2 does not validate SSL certificates, which allows remote attackers to bypass intended authentication and execute arbitrary API requests via a request without a certificate.

Heap-based buffer overflow in the PCNET controller in QEMU allows remote attackers to execute arbitrary code by sending a packet with TXSTATUSSTARTPACKET set and then a crafted packet with TXSTATUSDEVICEOWNS set.

A vulnerability in openstack-tripleo-heat-templates was found, which regardless of supplied values for credentials uses hardcoded rabbitmq credentails to guest/guest account. In the documentation users are strongly encouraged to change the default values for credentials, however changing these values using our instructions does not correctly set the values in the rabbitmq config.

A flaw was discovered in the pipeline ordering of the swift staticweb middleware in the swiftproxy config generated from the openstack-tripleo-heat-templates. The staticweb middleware was incorrectly configured before keystone and under some conditions may allow unauthenticated access to private data.

This issue was discovered by Christian Schwede and Emilien Macchi of Red Hat.

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.

Pivotal RabbitMQ, versions 3.7.x prior to 3.7.21 and 3.8.x prior to 3.8.1, and RabbitMQ for Pivotal Platform, 1.16.x versions prior to 1.16.7 and 1.17.x versions prior to 1.17.4, contain a web management plugin that is vulnerable to a denial of service attack. The "X-Reason" HTTP Header can be leveraged to insert a malicious Erlang format string that will expand and consume the heap, resulting in the server crashing.

A client with network access to the ironic-api service can bypass Keystone authentication and retrieve all information about any Node registered with Ironic, if they know (or are able to guess) the MAC address of a network card belonging to that Node, by sending a crafted POST request to the /v1/drivers/$DRIVERNAME/vendorpassthru resource.

The response will include the full Node details, including management passwords, even when /etc/ironic/policy.json is configured to hide passwords in API responses.

This vulnerability has been verified in all currently supported branches (liberty, mitaka, master) and traced back to code introduced in commit 3e568fbbbcc5748035c1448a0bdb26306470797c during the Juno development cycle. Therefore, it is likely that both juno and kilo branches (and their releases) are also affected.

Affected versions: >=2014.2, >=4.0.0 <=4.2.4, >=4.3.0 <=5.1.1
