CVSS: 5.5EPSS: 0%CPEs: 8EXPL: 1CVE-2023-42754 – Kernel: ipv4: null pointer dereference in ipv4_send_dest_unreach()
https://notcve.org/view.php?id=CVE-2023-42754
A NULL pointer dereference flaw was found in the Linux kernel ipv4 stack. The socket buffer (skb) was assumed to be associated with a device before calling __ip_options_compile, which is not always the case if the skb is re-routed by ipvs. This issue may allow a local user with CAP_NET_ADMIN privileges to crash the system. Se encontró una falla de desreferencia del puntero NULL en la pila ipv4 del kernel de Linux. Se suponía que el búfer de socket (skb) estaba asociado con un dispositivo antes de llamar a __ip_options_compile, lo que no siempre es el caso si ipvs redirige el skb. • 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-2023-42754 https://bugzilla.redhat.com/show_bug.cgi?id=2239845 https://lists.debian.org/debian-lts-announce/2024/01/msg00004.html https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/GISYSL3F6WIEVGHJGLC2MFNTUXHPTKQH https://lists.fedoraproject.org/archives/list/package-announc • CWE-476: NULL Pointer Dereference •

CVSS: 8.1EPSS: 0%CPEs: 6EXPL: 1CVE-2023-43804 – `Cookie` HTTP header isn't stripped on cross-origin redirects
https://notcve.org/view.php?id=CVE-2023-43804
urllib3 is a user-friendly HTTP client library for Python. urllib3 doesn't treat the `Cookie` HTTP header special or provide any helpers for managing cookies over HTTP, that is the responsibility of the user. However, it is possible for a user to specify a `Cookie` header and unknowingly leak information via HTTP redirects to a different origin if that user doesn't disable redirects explicitly. This issue has been patched in urllib3 version 1.26.17 or 2.0.5. urllib3 es una librería cliente HTTP fácil de usar para Python. urllib3 no trata el encabezado HTTP "Cookie" de manera especial ni proporciona ayuda para administrar las cookies a través de HTTP, eso es responsabilidad del usuario. Sin embargo, es posible que un usuario especifique un encabezado "Cookie" y, sin saberlo, filtre información a través de redireccionamientos HTTP a un origen diferente si ese usuario no deshabilita los redireccionamientos explícitamente. Este problema se solucionó en urllib3 versión 1.26.17 o 2.0.5. • https://github.com/JawadPy/CVE-2023-43804-Exploit https://github.com/urllib3/urllib3/commit/01220354d389cd05474713f8c982d05c9b17aafb https://github.com/urllib3/urllib3/commit/644124ecd0b6e417c527191f866daa05a5a2056d https://github.com/urllib3/urllib3/security/advisories/GHSA-v845-jxx5-vc9f https://lists.debian.org/debian-lts-announce/2023/10/msg00012.html https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/5F5CUBAN5XMEBVBZPHFITBLMJV5FIJJ5 https://lists.fedoraproject.org/archives/list/package-announc • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •

https://notcve.org/view.php?id=CVE-2023-4911
A buffer overflow was discovered in the GNU C Library's dynamic loader ld.so while processing the GLIBC_TUNABLES environment variable. This issue could allow a local attacker to use maliciously crafted GLIBC_TUNABLES environment variables when launching binaries with SUID permission to execute code with elevated privileges. Se descubrió un desbordamiento del búfer en el cargador dinámico ld.so de la librería GNU C mientras se procesaba la variable de entorno GLIBC_TUNABLES. Este problema podría permitir que un atacante local utilice variables de entorno GLIBC_TUNABLES manipuladas con fines malintencionados al iniciar archivos binarios con permiso SUID para ejecutar código con privilegios elevados.

CVSS: 7.8EPSS: 0%CPEs: 7EXPL: 0CVE-2023-5345 – Use-after-free in Linux kernel's fs/smb/client component
https://notcve.org/view.php?id=CVE-2023-5345
A use-after-free vulnerability in the Linux kernel's fs/smb/client component can be exploited to achieve local privilege escalation. In case of an error in smb3_fs_context_parse_param, ctx->password was freed but the field was not set to NULL which could lead to double free. We recommend upgrading past commit e6e43b8aa7cd3c3af686caf0c2e11819a886d705. Se puede explotar una vulnerabilidad de use-after-free en el componente fs/smb/client del kernel de Linux para lograr una escalada de privilegios local. En caso de un error en smb3_fs_context_parse_param, se liberó ctx->password pero el campo no se configuró en NULL, lo que podría provocar una doble liberación. Recomendamos actualizar al commit anterior e6e43b8aa7cd3c3af686caf0c2e11819a886d705. A flaw was found in the SMB client component in the Linux kernel. • http://packetstormsecurity.com/files/177029/Kernel-Live-Patch-Security-Notice-LSN-0100-1.html https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=e6e43b8aa7cd3c3af686caf0c2e11819a886d705 https://kernel.dance/e6e43b8aa7cd3c3af686caf0c2e11819a886d705 https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/GISYSL3F6WIEVGHJGLC2MFNTUXHPTKQH https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/GPMICQ2HVZO5UAM5KPXHAZKA2U3ZDOO6 https://lists.fedoraproject.org&#x • CWE-416: Use After Free •
