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

CVE-2020-14394 3.2 - Low - August 17, 2022

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.

Infinite Loop

This is a concurrency issue

CVE-2022-0866 5.3 - Medium - May 10, 2022

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 versions of WildFly 11+ when Elytron is enabled.

AuthZ

Infinite Loop

User credentials can be manipulated and stolen by Native CephFS consumers of OpenStack Manila, resulting in potential privilege escalation

CVE-2020-27781 7.1 - High - December 18, 2020

User credentials can be manipulated and stolen by Native CephFS consumers of OpenStack Manila, resulting in potential privilege escalation. An Open Stack Manila user can request access to a share to an arbitrary cephx user, including existing users. The access key is retrieved via the interface drivers. Then, all users of the requesting OpenStack project can view the access key. This enables the attacker to target any resource that the user has access to. This can be done to even "admin" users, compromising the ceph administrator. This flaw affects Ceph versions prior to 14.2.16, 15.x prior to 15.2.8, and 16.x prior to 16.2.0.
