CVSS: 7.8EPSS: 0%CPEs: 51EXPL: 0CVE-2023-3972 – Insights-client: unsafe handling of temporary files and directories
https://notcve.org/view.php?id=CVE-2023-3972
A vulnerability was found in insights-client. This security issue occurs because of insecure file operations or unsafe handling of temporary files and directories that lead to local privilege escalation. Before the insights-client has been registered on the system by root, an unprivileged local user or attacker could create the /var/tmp/insights-client directory (owning the directory with read, write, and execute permissions) on the system. After the insights-client is registered by root, an attacker could then control the directory content that insights are using by putting malicious scripts into it and executing arbitrary code as root (trivially bypassing SELinux protections because insights processes are allowed to disable SELinux system-wide). Se encontró una vulnerabilidad en insights-client. • https://access.redhat.com/errata/RHSA-2023:6264 https://access.redhat.com/errata/RHSA-2023:6282 https://access.redhat.com/errata/RHSA-2023:6283 https://access.redhat.com/errata/RHSA-2023:6284 https://access.redhat.com/errata/RHSA-2023:6795 https://access.redhat.com/errata/RHSA-2023:6796 https://access.redhat.com/errata/RHSA-2023:6798 https://access.redhat.com/errata/RHSA-2023:6811 https://access.redhat.com/security/cve/CVE-2023-3972 https://bugzilla.redhat.com/show • CWE-379: Creation of Temporary File in Directory with Insecure Permissions CWE-668: Exposure of Resource to Wrong Sphere •

CVSS: 7.8EPSS: 0%CPEs: 17EXPL: 0CVE-2023-5367 – Xorg-x11-server: out-of-bounds write in xichangedeviceproperty/rrchangeoutputproperty
https://notcve.org/view.php?id=CVE-2023-5367
A out-of-bounds write flaw was found in the xorg-x11-server. This issue occurs due to an incorrect calculation of a buffer offset when copying data stored in the heap in the XIChangeDeviceProperty function in Xi/xiproperty.c and in RRChangeOutputProperty function in randr/rrproperty.c, allowing for possible escalation of privileges or denial of service. Se encontró una falla de escritura fuera de los límites en el servidor xorg-x11. Este problema ocurre debido a un cálculo incorrecto de un desplazamiento del búfer al copiar datos almacenados en el montón en la función XIChangeDeviceProperty en Xi/xiproperty.c y en la función RRChangeOutputProperty en randr/rrproperty.c, lo que permite una posible escalada de privilegios o Denegación de Servicio (DoS). . This vulnerability allows local attackers to escalate privileges on affected installations of X.Org Server. • https://access.redhat.com/errata/RHSA-2023:6802 https://access.redhat.com/errata/RHSA-2023:6808 https://access.redhat.com/errata/RHSA-2023:7373 https://access.redhat.com/errata/RHSA-2023:7388 https://access.redhat.com/errata/RHSA-2023:7405 https://access.redhat.com/errata/RHSA-2023:7428 https://access.redhat.com/errata/RHSA-2023:7436 https://access.redhat.com/errata/RHSA-2023:7526 https://access.redhat.com/errata/RHSA-2023:7533 https://access.redhat.com/errata/RHSA • CWE-787: Out-of-bounds Write •
CVSS: 6.5EPSS: 0%CPEs: 11EXPL: 0CVE-2023-42669 – Samba: "rpcecho" development server allows denial of service via sleep() call on ad dc
https://notcve.org/view.php?id=CVE-2023-42669
A vulnerability was found in Samba's "rpcecho" development server, a non-Windows RPC server used to test Samba's DCE/RPC stack elements. This vulnerability stems from an RPC function that can be blocked indefinitely. The issue arises because the "rpcecho" service operates with only one worker in the main RPC task, allowing calls to the "rpcecho" server to be blocked for a specified time, causing service disruptions. This disruption is triggered by a "sleep()" call in the "dcesrv_echo_TestSleep()" function under specific conditions. Authenticated users or attackers can exploit this vulnerability to make calls to the "rpcecho" server, requesting it to block for a specified duration, effectively disrupting most services and leading to a complete denial of service on the AD DC. • https://access.redhat.com/errata/RHSA-2023:6209 https://access.redhat.com/errata/RHSA-2023:6744 https://access.redhat.com/errata/RHSA-2023:7371 https://access.redhat.com/errata/RHSA-2023:7408 https://access.redhat.com/errata/RHSA-2023:7464 https://access.redhat.com/errata/RHSA-2023:7467 https://access.redhat.com/security/cve/CVE-2023-42669 https://bugzilla.redhat.com/show_bug.cgi?id=2241884 https://bugzilla.samba.org/show_bug.cgi?id=15474 https://security.netapp.com& • CWE-400: Uncontrolled Resource Consumption •
