CVE-2023-6277 – Libtiff: out-of-memory in tiffopen via a craft file
https://notcve.org/view.php?id=CVE-2023-6277
An out-of-memory flaw was found in libtiff. Passing a crafted tiff file to TIFFOpen() API may allow a remote attacker to cause a denial of service via a craft input with size smaller than 379 KB. Se encontró un error de falta de memoria en libtiff. Pasar un archivo tiff manipulado a la API TIFFOpen() puede permitir que un atacante remoto provoque una denegación de servicio a través de una entrada artesanal con un tamaño inferior a 379 KB. • https://access.redhat.com/security/cve/CVE-2023-6277 https://bugzilla.redhat.com/show_bug.cgi?id=2251311 https://gitlab.com/libtiff/libtiff/-/issues/614 https://gitlab.com/libtiff/libtiff/-/merge_requests/545 https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/WJIN6DTSL3VODZUGWEUXLEL5DR53EZMV https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/Y7ZGN2MZXJ6E57W3L4YBM3ZPAU3T7T5C https://security.netapp.com/advisory/ntap-20240119-0002 • CWE-400: Uncontrolled Resource Consumption •
CVE-2023-6176 – Kernel: local dos vulnerability in scatterwalk_copychunks
https://notcve.org/view.php?id=CVE-2023-6176
A null pointer dereference flaw was found in the Linux kernel API for the cryptographic algorithm scatterwalk functionality. This issue occurs when a user constructs a malicious packet with specific socket configuration, which could allow a local user to crash the system or escalate their privileges on the system. Se encontró una falla de desreferencia de puntero nulo en la API del kernel de Linux para la funcionalidad de dispersión del algoritmo criptográfico. Este problema ocurre cuando un usuario construye un paquete malicioso con una configuración de socket específica, lo que podría permitir que un usuario local bloquee el sistema o aumente sus privilegios en el sistema. • http://packetstormsecurity.com/files/177029/Kernel-Live-Patch-Security-Notice-LSN-0100-1.html https://access.redhat.com/errata/RHSA-2024:2394 https://access.redhat.com/errata/RHSA-2024:2950 https://access.redhat.com/errata/RHSA-2024:3138 https://access.redhat.com/security/cve/CVE-2023-6176 https://bugzilla.redhat.com/show_bug.cgi?id=2219359 https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=cfaa80c91f6f99b9342b6557f0f0e1143e434066 • CWE-476: NULL Pointer Dereference •
CVE-2023-6121 – Kernel: nvme: info leak due to out-of-bounds read in nvmet_ctrl_find_get
https://notcve.org/view.php?id=CVE-2023-6121
An out-of-bounds read vulnerability was found in the NVMe-oF/TCP subsystem in the Linux kernel. This issue may allow a remote attacker to send a crafted TCP packet, triggering a heap-based buffer overflow that results in kmalloc data being printed and potentially leaked to the kernel ring buffer (dmesg). Se encontró una vulnerabilidad de lectura fuera de los límites en el subsistema NVMe-oF/TCP del kernel de Linux. Esta falla permite que un atacante remoto envíe un paquete TCP manipulado, lo que desencadena un desbordamiento del búfer que da como resultado que los datos kmalloc se impriman (y potencialmente se filtren) en el búfer de anillo del kernel (dmesg). • https://access.redhat.com/errata/RHSA-2024:2394 https://access.redhat.com/errata/RHSA-2024:2950 https://access.redhat.com/errata/RHSA-2024:3138 https://access.redhat.com/security/cve/CVE-2023-6121 https://bugzilla.redhat.com/show_bug.cgi?id=2250043 https://lists.debian.org/debian-lts-announce/2024/01/msg00005.html • CWE-125: Out-of-bounds Read •
CVE-2023-5868 – Postgresql: memory disclosure in aggregate function calls
https://notcve.org/view.php?id=CVE-2023-5868
A memory disclosure vulnerability was found in PostgreSQL that allows remote users to access sensitive information by exploiting certain aggregate function calls with 'unknown'-type arguments. Handling 'unknown'-type values from string literals without type designation can disclose bytes, potentially revealing notable and confidential information. This issue exists due to excessive data output in aggregate function calls, enabling remote users to read some portion of system memory. Se encontró una vulnerabilidad de divulgación de memoria en PostgreSQL que permite a usuarios remotos acceder a información confidencial explotando ciertas llamadas a funciones agregadas con argumentos de tipo "desconocido". El manejo de valores de tipo "desconocido" de cadenas literales sin designación de tipo puede revelar bytes, lo que potencialmente revela información importante y confidencial. • 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-686: Function Call With Incorrect Argument Type •
