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.

Oracle MySQL through 5.5.52, 5.6.x through 5.6.33, and 5.7.x through 5.7.15; MariaDB before 5.5.51, 10.0.x before 10.0.27, and 10.1.x before 10.1.17; and Percona Server before 5.5.51-38.1, 5.6.x before 5.6.32-78.0, and 5.7.x before 5.7.14-7 allow local users to create arbitrary configurations and bypass certain protection mechanisms by setting generallogfile to a my.cnf configuration. NOTE: this can be leveraged to execute arbitrary code with root privileges by setting malloclib. NOTE: the affected MySQL version information is from Oracle's October 2016 CPU. Oracle has not commented on third-party claims that the issue was silently patched in MySQL 5.5.52, 5.6.33, and 5.7.15.

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.

Quick emulator (QEMU) before 2.8 built with the Cirrus CLGD 54xx VGA Emulator support is vulnerable to an out-of-bounds access issue. The issue could occur while copying VGA data in cirrusbitbltcputovideo. A privileged user inside guest could use this flaw to crash the QEMU process OR potentially execute arbitrary code on 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 net/http library in net/http/transfer.go in Go before 1.4.3 does not properly parse HTTP headers, which allows remote attackers to conduct HTTP request smuggling attacks via a request that contains Content-Length and Transfer-Encoding header fields.

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.

Ansible before versions 2.1.4, 2.2.1 is vulnerable to an improper input validation in Ansible's handling of data sent from client systems. An attacker with control over a client system being managed by Ansible and the ability to send facts back to the Ansible server could use this flaw to execute arbitrary code on the Ansible server using the Ansible server privileges.

A flaw was found in all python-ecdsa versions before 0.13.3, where it did not correctly verify whether signatures used DER encoding. Without this verification, a malformed signature could be accepted, making the signature malleable. Without proper verification, an attacker could use a malleable signature to create false transactions.

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.

Quick emulator (QEMU) built with the Cirrus CLGD 54xx VGA emulator support is vulnerable to an out-of-bounds access issue. It could occur while copying VGA data via bitblt copy in backward mode. A privileged user inside a guest could use this flaw to crash the QEMU process resulting in DoS or potentially execute arbitrary code on the host with privileges of QEMU process on the host.

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.

A flaw was found in the KVM's AMD code for supporting SVM nested virtualization. The flaw occurs when processing the VMCB (virtual machine control block) provided by the L1 guest to spawn/handle a nested guest (L2). Due to improper validation of the "virtext" field, this issue could allow a malicious L1 to disable both VMLOAD/VMSAVE intercepts and VLS (Virtual VMLOAD/VMSAVE) for the L2 guest. As a result, the L2 guest would be allowed to read/write physical pages of the host, resulting in a crash of the entire system, leak of sensitive data or potential guest-to-host escape.

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.

A privilege escalation vulnerability exists in the oslo.privsep functionality of OpenStack git master 05194e7618 and prior. Overly permissive functionality within tools leveraging this library within a container can lead increased privileges.

A flaw was found in the way Samba maps domain users to local users. An authenticated attacker could use this flaw to cause possible privilege escalation.

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.

Impact

The patches introduced to fix https://github.com/Pylons/waitress/security/advisories/GHSA-m5ff-3wj3-8ph4 were not complete and still would allow an attacker to smuggle requests/split a HTTP request with invalid data.

This updates the existing CVE with ID: CVE-2019-16789

Patches

Waitress version 1.4.2 has been updated to now validate HTTP headers better to avoid the issue, completely fixing all known issues with whitespace.

Workarounds

There are no work-arounds, upgrading to Waitress 1.4.2 is highly recommended.

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.

Description An access-control flaw was found in the Octavia service when the cloud platform was deployed using Red Hat OpenStack Platform Director. An attacker could cause new amphorae to run based on any arbitrary image. This meant that a remote attacker could upload a new amphorae image and, if requested to spawn new amphorae, Octavia would then pick up the compromised image.

Mitigation To prevent this vulnerability: 1. Update Octavia's configuration setting (octavia.conf) to ampimageownerid = $UUIDOFSERVICEPROJECT on all Octavia nodes. 2. Enable the new configuration by restarting both octaviaworker and octaviahealthmanager.

A flaw was found in Ansible Engine, all versions 2.7.x, 2.8.x and 2.9.x prior to 2.7.17, 2.8.11, and 2.9.7 respectively, when using ansiblefacts as a subkey of itself and promoting it to a variable when inject is enabled, overwriting the ansiblefacts after the clean. An attacker could take advantage of this by altering the ansiblefacts, such as ansiblehosts, users and any other key data which would lead into privilege escalation or code injection.

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.
