CVSS: 7.8EPSS: 0%CPEs: 15EXPL: 2CVE-2023-35001 – Linux Kernel nftables Out-Of-Bounds Read/Write Vulnerability
https://notcve.org/view.php?id=CVE-2023-35001
Linux Kernel nftables Out-Of-Bounds Read/Write Vulnerability; nft_byteorder poorly handled vm register contents when CAP_NET_ADMIN is in any user or network namespace Vulnerabilidad de Lectura/Escritura en nftables Fuera de los Límites del kernel de Linux; nft_byteorder administra incorrectamente los contenidos de registro de VM cuando CAP_NET_ADMIN está en cualquier espacio de nombres de usuario o red An out-of-bounds (OOB) memory access flaw was found in the Netfilter module in the Linux kernel's nft_byteorder_eval in net/netfilter/nft_byteorder.c. A bound check failure allows a local attacker with CAP_NET_ADMIN access to cause a local privilege escalation issue due to incorrect data alignment. This vulnerability allows local attackers to escalate privileges on affected installations of Linux Kernel. An attacker must first obtain the ability to execute low-privileged code on the target system in order to exploit this vulnerability. The specific flaw exists within the processing of nft chains. The issue results from incorrect pointer scaling, which can result in a memory access past the end of an array. • https://github.com/synacktiv/CVE-2023-35001 https://github.com/syedhafiz1234/nftables-oob-read-write-exploit-CVE-2023-35001- http://packetstormsecurity.com/files/173757/Kernel-Live-Patch-Security-Notice-LSN-0096-1.html http://packetstormsecurity.com/files/174577/Kernel-Live-Patch-Security-Notice-LSN-0097-1.html http://www.openwall.com/lists/oss-security/2023/07/05/3 https://lists.debian.org/debian-lts-announce/2023/08/msg00001.html https://lists.debian.org/debian-lts-announce/2024/01/m • CWE-125: Out-of-bounds Read CWE-787: Out-of-bounds Write •

https://notcve.org/view.php?id=CVE-2023-31248
Linux Kernel nftables Use-After-Free Local Privilege Escalation Vulnerability; `nft_chain_lookup_byid()` failed to check whether a chain was active and CAP_NET_ADMIN is in any user or network namespace Vulnerabilidad de Escalada de Privilegios Locales de Use-After-Free de Linux nftables; 'nft_chain_lookup_byid()' no pudo comprobar si una cadena estaba activa y CAP_NET_ADMIN está en cualquier espacio de nombres de usuario o red A use-after-free flaw was found in the Linux kernel's Netfilter module in net/netfilter/nf_tables_api.c in nft_chain_lookup_byid. This flaw allows a local attacker to cause a local privilege escalation issue due to a missing cleanup. This vulnerability allows local attackers to escalate privileges on affected installations of Linux Kernel. An attacker must first obtain the ability to execute low-privileged code on the target system in order to exploit this vulnerability. The specific flaw exists within the handling of nft_chains. The issue results from the lack of validating the status of a chain while processing lookup on the chain. • http://packetstormsecurity.com/files/173757/Kernel-Live-Patch-Security-Notice-LSN-0096-1.html http://packetstormsecurity.com/files/174577/Kernel-Live-Patch-Security-Notice-LSN-0097-1.html http://www.openwall.com/lists/oss-security/2023/07/05/2 https://lists.debian.org/debian-lts-announce/2023/08/msg00001.html https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/RGZC5XOANA75OJ4XARBBXYSLDKUIJI5E https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.or • CWE-416: Use After Free •

A heap-based buffer overflow vulnerability was found in coders/tiff.c in ImageMagick. This issue may allow a local attacker to trick the user into opening a specially crafted file, resulting in an application crash and denial of service. Se encontró una vulnerabilidad de desbordamiento del búfer en coders/tiff.c en ImageMagick. Este problema puede permitir que un atacante local engañe al usuario para que abra un archivo especialmente manipulado, lo que provocará un bloqueo de la aplicación y una denegación de servicio. • https://access.redhat.com/security/cve/CVE-2023-3428 https://bugzilla.redhat.com/show_bug.cgi?id=2218369 • CWE-122: Heap-based Buffer Overflow CWE-787: Out-of-bounds Write •

In Django 3.2 before 3.2.20, 4 before 4.1.10, and 4.2 before 4.2.3, EmailValidator and URLValidator are subject to a potential ReDoS (regular expression denial of service) attack via a very large number of domain name labels of emails and URLs. A regular expression denial of service vulnerability has been found in Django. Email and URL validators are vulnerable to this flaw when processing a very large number of domain name labels of emails and URLs. • https://docs.djangoproject.com/en/4.2/releases/security https://groups.google.com/forum/#%21forum/django-announce https://lists.debian.org/debian-lts-announce/2023/07/msg00022.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/NRDGTUN4LTI6HG4TWR3JYLSFVXPZT42A https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/XG5DYKPNDCEHJQ3TKPJQO7QGSR4FAYMS https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/ZQJO • CWE-1333: Inefficient Regular Expression Complexity •
CVSS: 7.5EPSS: 0%CPEs: 5EXPL: 1CVE-2023-30589 – nodejs: HTTP Request Smuggling via Empty headers separated by CR
https://notcve.org/view.php?id=CVE-2023-30589
The llhttp parser in the http module in Node v20.2.0 does not strictly use the CRLF sequence to delimit HTTP requests. This can lead to HTTP Request Smuggling (HRS). The CR character (without LF) is sufficient to delimit HTTP header fields in the llhttp parser. According to RFC7230 section 3, only the CRLF sequence should delimit each header-field. This impacts all Node.js active versions: v16, v18, and, v20 A vulnerability has been identified in the Node.js, where llhttp parser in the http module in Node.js does not strictly use the CRLF sequence to delimit HTTP requests. This can lead to HTTP Request Smuggling (HRS). • https://hackerone.com/reports/2001873 https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/HMEELCREWMRT6NS7HWXLA6XFLLMO36HE https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/IV326O2X4BE3SINX5FJHMAKVHUAA4ZYF https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/UEJWL67XR67JAGEL2ZK22NA3BRKNMZNY https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/VCVG4TQRGTK4LKAZKVEQAUEJM7DUACYE https://lists.fedoraproject. •
