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 •

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. •

CVSS: 7.1EPSS: 0%CPEs: 7EXPL: 1CVE-2023-34241 – CUPS vulnerable to use-after-free in cupsdAcceptClient()
https://notcve.org/view.php?id=CVE-2023-34241
OpenPrinting CUPS is a standards-based, open source printing system for Linux and other Unix-like operating systems. Starting in version 2.0.0 and prior to version 2.4.6, CUPS logs data of free memory to the logging service AFTER the connection has been closed, when it should have logged the data right before. This is a use-after-free bug that impacts the entire cupsd process. The exact cause of this issue is the function `httpClose(con->http)` being called in `scheduler/client.c`. The problem is that httpClose always, provided its argument is not null, frees the pointer at the end of the call, only for cupsdLogClient to pass the pointer to httpGetHostname. This issue happens in function `cupsdAcceptClient` if LogLevel is warn or higher and in two scenarios: there is a double-lookup for the IP Address (HostNameLookups Double is set in `cupsd.conf`) which fails to resolve, or if CUPS is compiled with TCP wrappers and the connection is refused by rules from `/etc/hosts.allow` and `/etc/hosts.deny`. Version 2.4.6 has a patch for this issue. • http://www.openwall.com/lists/oss-security/2023/06/23/10 http://www.openwall.com/lists/oss-security/2023/06/26/1 https://github.com/OpenPrinting/cups/commit/9809947a959e18409dcf562a3466ef246cb90cb2 https://github.com/OpenPrinting/cups/releases/tag/v2.4.6 https://github.com/OpenPrinting/cups/security/advisories/GHSA-qjgh-5hcq-5f25 https://lists.debian.org/debian-lts-announce/2023/06/msg00038.html https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/7I7DWGYGE • CWE-416: Use After Free •
