All Samba versions 4.x.x before 4.9.17, 4.10.x before 4.10.11 and 4.11.x before 4.11.3 have an issue, where the S4U (MS-SFU) Kerberos delegation model includes a feature allowing for a subset of clients to be opted out of constrained delegation in any way, either S4U2Self or regular Kerberos authentication, by forcing all tickets for these clients to be non-forwardable. In AD this is implemented by a user attribute delegation_not_allowed (aka not-delegated), which translates to disallow-forwardable. However the Samba AD DC does not do that for S4U2Self and does set the forwardable flag even if the impersonated client has the not-delegated flag set.

In the Linux kernel before 5.3.11, there is an info-leak bug that can be caused by a malicious USB device in the drivers/net/can/usb/peak_usb/pcan_usb_core.c driver, aka CID-f7a1337f0d29.

The containers/image library used by the container tools Podman, Buildah, and Skopeo in Red Hat Enterprise Linux version 8 and CRI-O in OpenShift Container Platform, does not enforce TLS connections to the container registry authorization service. An attacker could use this vulnerability to launch a MiTM attack and steal login credentials or bearer tokens.

A vulnerability was found in Infinispan such that the invokeAccessibly method from the public class ReflectionUtil allows any application class to invoke private methods in any class with Infinispan's privileges. The attacker can use reflection to introduce new, malicious behavior into the application.

Dolibarr ERP/CRM 3.3.1 does not properly validate user input in viewimage.php and barcode.lib.php which allows remote attackers to execute arbitrary commands.

SQL injection vulnerability in Dolibarr ERP/CRM 3.3.1 allows remote attackers to execute arbitrary SQL commands via the 'pays' parameter in fiche.php.

Perdition before 2.2 may have weak security when handling outbound connections, caused by an error in the STARTTLS IMAP and POP server. ssl_outgoing_ciphers not being applied to STARTTLS connections
