A NULL pointer dereference, or possible use-after-free flaw was found in Samba AD LDAP server in versions before 4.10.17, before 4.11.11 and before 4.12.4. Although some versions of Samba shipped with Red Hat Enterprise Linux do not support Samba in AD mode, the affected code is shipped with the libldb package. This flaw allows an authenticated user to possibly trigger a use-after-free or NULL pointer dereference. The highest threat from this vulnerability is to system availability.

A flaw was found in the use of insufficiently random values in Ansible. Two random password lookups of the same length generate the equal value as the template caching action for the same file since no re-evaluation happens. The highest threat from this vulnerability would be that all passwords are exposed at once for the file. This flaw affects Ansible Engine versions before 2.9.6.

A flaw was found in automationbroker/apb container in versions up to and including 2.0.4-1. This container grants all users sudoer permissions allowing an unauthorized user with access to the running container the ability to escalate their own privileges. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability.

A flaw was found in ActiveMQ Artemis management API from version 2.7.0 up until 2.12.0, where a user inadvertently stores passwords in plaintext in the Artemis shadow file (etc/artemis-users.properties file) when executing the `resetUsers` operation. A local attacker can use this flaw to read the contents of the Artemis shadow file.

A vulnerability was found in DPDK versions 19.11 and above. A malicious container that has direct access to the vhost-user socket can keep sending VHOST_USER_GET_INFLIGHT_FD messages, causing a resource leak (file descriptors and virtual memory), which may result in a denial of service.

A flaw was found in DPDK version 19.11 and above that allows a malicious guest to cause a segmentation fault of the vhost-user backend application running on the host, which could result in a loss of connectivity for the other guests running on that host. This is caused by a missing validity check of the descriptor address in the function `virtio_dev_rx_batch_packed()`.

A vulnerability was found in DPDK versions 18.11 and above. The vhost-crypto library code is missing validations for user-supplied values, potentially allowing an information leak through an out-of-bounds memory read.

A memory corruption issue was found in DPDK versions 17.05 and above. This flaw is caused by an integer truncation on the index of a payload. Under certain circumstances, the index (a UInt) is copied and truncated into a uint16, which can lead to out of bound indexing and possible memory corruption.

A vulnerability was found in DPDK versions 18.05 and above. A missing check for an integer overflow in vhost_user_set_log_base() could result in a smaller memory map than requested, possibly allowing memory corruption.

A flaw was found in the fabric8-maven-plugin 4.0.0 and later. When using a wildfly-swarm or thorntail custom configuration, a malicious YAML configuration file on the local machine executing the maven plug-in could allow for deserialization of untrusted data resulting in arbitrary code execution. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability.

A flaw was found in the Linux kernel's implementation of GRO in versions before 5.2. This flaw allows an attacker with local access to crash the system.

A flaw was found in Undertow in versions before 2.1.1.Final, regarding the processing of invalid HTTP requests with large chunk sizes. This flaw allows an attacker to take advantage of HTTP request smuggling.

A flaw was found in Wildfly before wildfly-embedded-13.0.0.Final, where the embedded managed process API has an exposed setting of the Thread Context Classloader (TCCL). This setting is exposed as a public method, which can bypass the security manager. The highest threat from this vulnerability is to confidentiality.

A potential DoS flaw was found in the virtio-fs shared file system daemon (virtiofsd) implementation of the QEMU version >= v5.0. Virtio-fs is meant to share a host file system directory with a guest via virtio-fs device. If the guest opens the maximum number of file descriptors under the shared directory, a denial of service may occur. This flaw allows a guest user/process to cause this denial of service on the host.

A flaw was found in Red Hat Satellite's Job Invocation, where the "User Input" entry was not properly restricted to the view. This flaw allows a malicious Satellite user to scan through the Job Invocation, with the ability to search for passwords and other sensitive data. This flaw affects tfm-rubygem-foreman_ansible versions before 4.0.3.4.

A content spoofing vulnerability was found in the openshift/console 3.11 and 4.x. This flaw allows an attacker to craft a URL and inject arbitrary text onto the error page that appears to be from the OpenShift instance. This attack could potentially convince a user that the inserted text is legitimate.

A flaw was found in WildFly Elytron version 1.11.3.Final and before. When using WildFly Elytron FORM authentication with a session ID in the URL, an attacker could perform a session fixation attack. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability.

A flaw was found in grub2, prior to version 2.06. An attacker may use the GRUB 2 flaw to hijack and tamper the GRUB verification process. This flaw also allows the bypass of Secure Boot protections. In order to load an untrusted or modified kernel, an attacker would first need to establish access to the system such as gaining physical access, obtain the ability to alter a pxe-boot network, or have remote access to a networked system with root access. With this access, an attacker could then craft a string to cause a buffer overflow by injecting a malicious payload that leads to arbitrary code execution within GRUB. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability.

A flaw was found in OpenShift Container Platform version 4.1 and later. Sensitive information was found to be logged by the image registry operator allowing an attacker able to gain access to those logs, to read and write to the storage backing the internal image registry. The highest threat from this vulnerability is to data integrity.

A NULL pointer dereference flaw was found in the Linux kernel's SELinux subsystem in versions before 5.7. This flaw occurs while importing the Commercial IP Security Option (CIPSO) protocol's category bitmap into the SELinux extensible bitmap via the' ebitmap_netlbl_import' routine. While processing the CIPSO restricted bitmap tag in the 'cipso_v4_parsetag_rbm' routine, it sets the security attribute to indicate that the category bitmap is present, even if it has not been allocated. This issue leads to a NULL pointer dereference issue while importing the same category bitmap into SELinux. This flaw allows a remote network user to crash the system kernel, resulting in a denial of service.
