CVSS: 7.0EPSS: 0%CPEs: 6EXPL: 3CVE-2023-4504 – OpenPrinting CUPS/libppd Postscript Parsing Heap Overflow
https://notcve.org/view.php?id=CVE-2023-4504
Due to failure in validating the length provided by an attacker-crafted PPD PostScript document, CUPS and libppd are susceptible to a heap-based buffer overflow and possibly code execution. This issue has been fixed in CUPS version 2.4.7, released in September of 2023. Debido a un error al validar la longitud proporcionada por un documento PPD PostScript creado por un atacante, CUPS y libppd son susceptibles a un desbordamiento del búfer y posiblemente a la ejecución de código. Este problema se solucionó en la versión 2.4.7 de CUPS, lanzada en septiembre de 2023. • https://github.com/OpenPrinting/cups/releases/tag/v2.4.7 https://github.com/OpenPrinting/cups/security/advisories/GHSA-pf5r-86w9-678h https://github.com/OpenPrinting/libppd/security/advisories/GHSA-4f65-6ph5-qwh6 https://lists.debian.org/debian-lts-announce/2023/09/msg00041.html https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/5WHEJIYMMAIXU2EC35MGTB5LGGO2FFJE https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/5WVS4I7JG3LISFPKTM6ADKJXXEPEEWBQ • CWE-122: Heap-based Buffer Overflow CWE-787: Out-of-bounds Write •

https://notcve.org/view.php?id=CVE-2023-43669
The Tungstenite crate before 0.20.1 for Rust allows remote attackers to cause a denial of service (minutes of CPU consumption) via an excessive length of an HTTP header in a client handshake. The length affects both how many times a parse is attempted (e.g., thousands of times) and the average amount of data for each parse attempt (e.g., millions of bytes). El Tungstenite crate anterior a la versión 0.20.1 para Rust permite a atacantes remotos provocar una denegación del servicio (de minutos de consumo de la CPU) a través de una longitud excesiva de un encabezado HTTP en el handshake del cliente. La longitud afecta tanto a cuántas veces se intenta un análisis (por ejemplo, miles de veces) y la cantidad promedio de datos para cada intento de análisis (por ejemplo, millones de bytes). • https://bugzilla.redhat.com/show_bug.cgi?id=2240110 https://bugzilla.suse.com/show_bug.cgi?id=1215563 https://crates.io/crates/tungstenite/versions https://cwe.mitre.org/data/definitions/407.html https://github.com/advisories/GHSA-9mcr-873m-xcxp https://github.com/github/advisory-database/pull/2752 https://github.com/snapview/tungstenite-rs/commit/8b3ecd3cc0008145ab4bc8d0657c39d09db8c7e2 https://github.com/snapview/tungstenite-rs/issues/376 https://lists.fedoraproject.org/archives/list/package-an •
CVSS: 7.5EPSS: 0%CPEs: 18EXPL: 0CVE-2023-4236 – named may terminate unexpectedly under high DNS-over-TLS query load
https://notcve.org/view.php?id=CVE-2023-4236
A flaw in the networking code handling DNS-over-TLS queries may cause `named` to terminate unexpectedly due to an assertion failure. This happens when internal data structures are incorrectly reused under significant DNS-over-TLS query load. This issue affects BIND 9 versions 9.18.0 through 9.18.18 and 9.18.11-S1 through 9.18.18-S1. Una falla en el código de red que maneja consultas DNS sobre TLS puede causar que "named" finalice inesperadamente debido a una falla de aserción. Esto sucede cuando las estructuras de datos internas se reutilizan incorrectamente bajo una carga significativa de consultas DNS sobre TLS. Este problema afecta a las versiones 9.18.0 a 9.18.18 y 9.18.11-S1 a 9.18.18-S1 de BIND 9. • http://www.openwall.com/lists/oss-security/2023/09/20/2 https://kb.isc.org/docs/cve-2023-4236 https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/IPJLLTJCSDJJII7IIZPLTBQNWP7MZH7F https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/U35OARLQCPMVCBBPHWBXY5M6XJLD2TZ5 https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/VSK5V4W4OHPM3JTJGWAQD6CZW7SFD75B https://security.netapp.com/advisory/ntap-20231013-0004 https:/& • CWE-617: Reachable Assertion •
CVSS: 7.5EPSS: 0%CPEs: 38EXPL: 0CVE-2023-3341 – A stack exhaustion flaw in control channel code may cause named to terminate unexpectedly
https://notcve.org/view.php?id=CVE-2023-3341
The code that processes control channel messages sent to `named` calls certain functions recursively during packet parsing. Recursion depth is only limited by the maximum accepted packet size; depending on the environment, this may cause the packet-parsing code to run out of available stack memory, causing `named` to terminate unexpectedly. Since each incoming control channel message is fully parsed before its contents are authenticated, exploiting this flaw does not require the attacker to hold a valid RNDC key; only network access to the control channel's configured TCP port is necessary. This issue affects BIND 9 versions 9.2.0 through 9.16.43, 9.18.0 through 9.18.18, 9.19.0 through 9.19.16, 9.9.3-S1 through 9.16.43-S1, and 9.18.0-S1 through 9.18.18-S1. El código que procesa los mensajes del canal de control enviados a "named" llama a ciertas funciones de forma recursiva durante el análisis de paquetes. La profundidad de la recursividad sólo está limitada por el tamaño máximo de paquete aceptado; Dependiendo del entorno, esto puede provocar que el código de análisis de paquetes se quede sin memoria disponible, lo que provocará que "named" finalice inesperadamente. • http://www.openwall.com/lists/oss-security/2023/09/20/2 https://kb.isc.org/docs/cve-2023-3341 https://lists.debian.org/debian-lts-announce/2024/01/msg00021.html https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/IPJLLTJCSDJJII7IIZPLTBQNWP7MZH7F https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/U35OARLQCPMVCBBPHWBXY5M6XJLD2TZ5 https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/VSK5V4W4OHPM3JTJGWAQD6CZW7SFD • CWE-20: Improper Input Validation CWE-787: Out-of-bounds Write •
