An infinite loop flaw was found in the USB xHCI controller emulation of QEMU while computing the length of the Transfer Request Block (TRB) Ring. This flaw allows a privileged guest user to hang the QEMU process on the host, resulting in a denial of service.

Jenkins Openstack Heat Plugin 1.5 and earlier does not perform permission checks in methods implementing form validation, allowing attackers with Overall/Read permission to check for the existence of an attacker-specified file path on the Jenkins controller file system.

A missing permission check in Jenkins Openstack Heat Plugin 1.5 and earlier allows attackers with Overall/Read permission to connect to an attacker-specified URL.

A cross-site request forgery (CSRF) vulnerability in Jenkins Openstack Heat Plugin 1.5 and earlier allows attackers to connect to an attacker-specified URL.

An Incorrect Permission Assignment for Critical Resource flaw was found in Horizon on Red Hat OpenStack. Horizon session cookies are created without the HttpOnly flag despite HorizonSecureCookies being set to true in the environmental files, possibly leading to a loss of confidentiality and integrity.

This is a concurrency issue that can result in the wrong caller principal being returned from the session context of an EJB that is configured with a RunAs principal. In particular, the org.jboss.as.ejb3.component.EJBComponent class has an incomingRunAsIdentity field. This field is used by the org.jboss.as.ejb3.security.RunAsPrincipalInterceptor to keep track of the current identity prior to switching to a new identity created using the RunAs principal. The exploit consist that the EJBComponent#incomingRunAsIdentity field is currently just a SecurityIdentity. This means in a concurrent environment, where multiple users are repeatedly invoking an EJB that is configured with a RunAs principal, it's possible for the wrong the caller principal to be returned from EJBComponent#getCallerPrincipal. Similarly, it's also possible for EJBComponent#isCallerInRole to return the wrong value. Both of these methods rely on incomingRunAsIdentity. Affects all versions of JBoss EAP from 7.1.0 and all v…

In cifs-utils through 6.14, a stack-based buffer overflow when parsing the mount.cifs ip= command-line argument could lead to local attackers gaining root privileges.

An information exposure flaw in openstack-tripleo-heat-templates allows an external user to discover the internal IP or hostname. An attacker could exploit this by checking the www_authenticate_uri parameter (which is visible to all end users) in configuration files. This would give sensitive information which may aid in additional system exploitation. This flaw affects openstack-tripleo-heat-templates versions prior to 11.6.1.

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 "virt_ext" 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.

A flaw was found in Ansible Engine's ansible-connection module, where sensitive information such as the Ansible user credentials is disclosed by default in the traceback error message. The highest threat from this vulnerability is to confidentiality.
