CVE-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. •
CVE-2023-1206 – kernel: hash collisions in the IPv6 connection lookup table
https://notcve.org/view.php?id=CVE-2023-1206
A hash collision flaw was found in the IPv6 connection lookup table in the Linux kernel’s IPv6 functionality when a user makes a new kind of SYN flood attack. A user located in the local network or with a high bandwidth connection can increase the CPU usage of the server that accepts IPV6 connections up to 95%. • https://bugzilla.redhat.com/show_bug.cgi?id=2175903 https://lists.debian.org/debian-lts-announce/2023/10/msg00027.html https://lists.debian.org/debian-lts-announce/2024/01/msg00004.html https://security.netapp.com/advisory/ntap-20230929-0006 https://www.debian.org/security/2023/dsa-5480 https://www.debian.org/security/2023/dsa-5492 https://access.redhat.com/security/cve/CVE-2023-1206 • CWE-400: Uncontrolled Resource Consumption •

CVE-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 •
