https://notcve.org/view.php?id=CVE-2023-6134
A flaw was found in Keycloak that prevents certain schemes in redirects, but permits them if a wildcard is appended to the token. This issue could allow an attacker to submit a specially crafted request leading to cross-site scripting (XSS) or further attacks. This flaw is the result of an incomplete fix for CVE-2020-10748. Se encontró una falla en Keycloak que impide ciertos esquemas en las redirecciones, pero los permite si se agrega un comodín al token. Este problema podría permitir que un atacante envíe una solicitud especialmente manipulada que dé lugar a cross-site scripting (XSS) o más ataques. • https://access.redhat.com/errata/RHSA-2023:7854 https://access.redhat.com/errata/RHSA-2023:7855 https://access.redhat.com/errata/RHSA-2023:7856 https://access.redhat.com/errata/RHSA-2023:7857 https://access.redhat.com/errata/RHSA-2023:7858 https://access.redhat.com/errata/RHSA-2023:7860 https://access.redhat.com/errata/RHSA-2023:7861 https://access.redhat.com/errata/RHSA-2024:0798 https://access.redhat.com/errata/RHSA-2024:0799 https://access.redhat.com/errata/RHSA • CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') •
CVSS: 8.8EPSS: 1%CPEs: 49EXPL: 0CVE-2023-5869 – Postgresql: buffer overrun from integer overflow in array modification
https://notcve.org/view.php?id=CVE-2023-5869
A flaw was found in PostgreSQL that allows authenticated database users to execute arbitrary code through missing overflow checks during SQL array value modification. This issue exists due to an integer overflow during array modification where a remote user can trigger the overflow by providing specially crafted data. This enables the execution of arbitrary code on the target system, allowing users to write arbitrary bytes to memory and extensively read the server's memory. Se encontró una falla en PostgreSQL que permite a los usuarios de bases de datos autenticados ejecutar código arbitrario al faltar verificaciones de desbordamiento durante la modificación del valor de la matriz SQL. Este problema existe debido a un desbordamiento de enteros durante la modificación de la matriz, donde un usuario remoto puede desencadenar el desbordamiento proporcionando datos especialmente manipulados. • https://access.redhat.com/errata/RHSA-2023:7545 https://access.redhat.com/errata/RHSA-2023:7579 https://access.redhat.com/errata/RHSA-2023:7580 https://access.redhat.com/errata/RHSA-2023:7581 https://access.redhat.com/errata/RHSA-2023:7616 https://access.redhat.com/errata/RHSA-2023:7656 https://access.redhat.com/errata/RHSA-2023:7666 https://access.redhat.com/errata/RHSA-2023:7667 https://access.redhat.com/errata/RHSA-2023:7694 https://access.redhat.com/errata/RHSA • CWE-190: Integer Overflow or Wraparound •

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).

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). .
