An authenticated user may receive all the roles assigned to the user's project regardless of the federation mapping when there are rules in which group-based assignments are not used. For example, by requesting an admin user to get a role in their project, the user may be granted the admin privileges for new scoped tokens. All setups using the Keystone federation with projects auto-provisioning and no group based assignments rules are affected.

Affected versions: 10.0.0, 10.0.1, 11.0.0

An off-by-one error was found in the SCSI Device emulation in QEMU. It could occur in hw/scsi/scsi-disk.c:modesensepage() while processing MODE SELECT commands if 'page' was set to MODEPAGEALLS (0x3f). Specifically, 'page' was used to index the stack-allocated 'modesensevalid' buffer (size=0x3f), causing an off-by-one error when trying to access the last element. A malicious guest could use this flaw to potentially crash QEMU, resulting in a denial of service condition.

An out-of-bounds read/write access flaw was found in the USB emulator of the QEMU in versions before 5.2.0. This issue occurs while processing USB packets from a guest when USBDevice 'setuplen' exceeds its 'databuf[4096]' in the dotokenin, dotokenout routines. This flaw allows a guest user to crash the QEMU process, resulting in a denial of service, or the potential execution of arbitrary code with the privileges of the QEMU process on the host.

1 / 4

Remedy

Using Libvirt management interface to manage guest VMs significantly reduces impact of this issue. Libvirt starts each guest process with an unprivileged system user(ex. qemu) privileges and further confines the process with strict sVirt and SELinux policies. * https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/7/html/virtualization_security_guide/

SQL Injection
CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:H

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.

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.

The temporary directory is created in /tmp leaves the s ts unencrypted. On Operating Systems which /tmp is not a tmpfs but part of the root partition, the directory is only cleared on boot and the decryp emains when the host is switched off. The system will be vulnerable when the system is not running. So decrypted data must be cleared as soon as possible and the data which normally is encrypted ble.

Remedy

Currently, there is no mitigation for this issue except by removing manually the temporary created file after every run.

AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:H

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.
