CVSS: 7.8EPSS: 0%CPEs: 5EXPL: 2CVE-2023-42753 – Kernel: netfilter: potential slab-out-of-bound access due to integer underflow
https://notcve.org/view.php?id=CVE-2023-42753
An array indexing vulnerability was found in the netfilter subsystem of the Linux kernel. A missing macro could lead to a miscalculation of the `h->nets` array offset, providing attackers with the primitive to arbitrarily increment/decrement a memory buffer out-of-bound. This issue may allow a local user to crash the system or potentially escalate their privileges on the system. Se encontró una vulnerabilidad de indexación de matrices en el subsistema netfilter del kernel de Linux. Una macro faltante podría provocar un error de cálculo del desplazamiento de la matriz `h->nets`, proporcionando a los atacantes la primitiva de incrementar/disminuir arbitrariamente un búfer de memoria fuera de límites. • http://packetstormsecurity.com/files/175963/Kernel-Live-Patch-Security-Notice-LSN-0099-1.html https://access.redhat.com/errata/RHSA-2023:7370 https://access.redhat.com/errata/RHSA-2023:7379 https://access.redhat.com/errata/RHSA-2023:7382 https://access.redhat.com/errata/RHSA-2023:7389 https://access.redhat.com/errata/RHSA-2023:7411 https://access.redhat.com/errata/RHSA-2023:7418 https://access.redhat.com/errata/RHSA-2023:7539 https://access.redhat.com/errata/RHSA-2023:7558 h • CWE-787: Out-of-bounds Write •
CVSS: 9.0EPSS: 0%CPEs: 3EXPL: 1CVE-2023-3550 – Stored XSS leads to privilege escalation in MediaWiki v1.40.0
https://notcve.org/view.php?id=CVE-2023-3550
Mediawiki v1.40.0 does not validate namespaces used in XML files. Therefore, if the instance administrator allows XML file uploads, a remote attacker with a low-privileged user account can use this exploit to become an administrator by sending a malicious link to the instance administrator. Mediawiki v1.40.0 no valida los espacios de nombres utilizados en archivos XML. Por lo tanto, si el administrador de la instancia permite la carga de archivos XML, un atacante remoto con una cuenta de usuario con pocos privilegios puede utilizar este exploit para convertirse en administrador enviando un enlace malicioso al administrador de la instancia. • https://fluidattacks.com/advisories/blondie https://lists.debian.org/debian-lts-announce/2023/11/msg00027.html https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/FU2FGUXXK6TMV6R52VRECLC6XCSQQISY https://www.debian.org/security/2023/dsa-5520 https://www.mediawiki.org/wiki/MediaWiki • CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') •

Due to failure in validating the length provided by an attacker-crafted PPD PostScript document, CUPS and libppd are susceptible to a heap-based buffer overflow and possibly code execution. This issue has been fixed in CUPS version 2.4.7, released in September of 2023. Debido a un error al validar la longitud proporcionada por un documento PPD PostScript creado por un atacante, CUPS y libppd son susceptibles a un desbordamiento del búfer y posiblemente a la ejecución de código.
