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: 6.5EPSS: 0%CPEs: 38EXPL: 1CVE-2023-4527 – Glibc: stack read overflow in getaddrinfo in no-aaaa mode
https://notcve.org/view.php?id=CVE-2023-4527
A flaw was found in glibc. When the getaddrinfo function is called with the AF_UNSPEC address family and the system is configured with no-aaaa mode via /etc/resolv.conf, a DNS response via TCP larger than 2048 bytes can potentially disclose stack contents through the function returned address data, and may cause a crash. Se encontró una falla en glibc. Cuando se llama a la función getaddrinfo con la familia de direcciones AF_UNSPEC y el sistema está configurado con el modo no-aaaa a través de /etc/resolv.conf, una respuesta DNS a través de TCP de más de 2048 bytes puede potencialmente revelar el contenido de la pila de memoria a través de los datos de la dirección devuelta por la función, y puede provocar un crash. • http://www.openwall.com/lists/oss-security/2023/09/25/1 https://access.redhat.com/errata/RHSA-2023:5453 https://access.redhat.com/errata/RHSA-2023:5455 https://access.redhat.com/security/cve/CVE-2023-4527 https://bugzilla.redhat.com/show_bug.cgi?id=2234712 https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/4DBUQRRPB47TC3NJOUIBVWUGFHBJAFDL https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/DFG4P76UHHZEWQ26FWBXG76N2QLKKPZA https: • CWE-121: Stack-based Buffer Overflow CWE-125: Out-of-bounds Read •

https://notcve.org/view.php?id=CVE-2023-4813
A flaw was found in glibc. In an uncommon situation, the gaih_inet function may use memory that has been freed, resulting in an application crash. This issue is only exploitable when the getaddrinfo function is called and the hosts database in /etc/nsswitch.conf is configured with SUCCESS=continue or SUCCESS=merge. Se encontró una falla en glibc. En una situación poco común, la función gaih_inet puede utilizar memoria que se ha liberado, lo que provoca un bloqueo de la aplicación. • http://www.openwall.com/lists/oss-security/2023/10/03/8 https://access.redhat.com/errata/RHSA-2023:5453 https://access.redhat.com/errata/RHSA-2023:5455 https://access.redhat.com/errata/RHSA-2023:7409 https://access.redhat.com/security/cve/CVE-2023-4813 https://bugzilla.redhat.com/show_bug.cgi?id=2237798 https://security.netapp.com/advisory/ntap-20231110-0003 • CWE-416: Use After Free •

Heap buffer overflow in libwebp in Google Chrome prior to 116.0.5845.187 and libwebp 1.3.2 allowed a remote attacker to perform an out of bounds memory write via a crafted HTML page. (Chromium security severity: Critical) El desbordamiento del búfer de memoria en libwebp en Google Chrome anterior a 116.0.5845.187 y libwebp 1.3.2 permitía a un atacante remoto realizar una escritura en memoria fuera de los límites a través de una página HTML manipulada. (Severidad de seguridad de Chromium: crítica) A heap-based buffer flaw was found in the way libwebp, a library used to process "WebP" image format data, processes certain specially formatted WebP images. An attacker could use this flaw to crash or execute remotely arbitrary code in an application such as a web browser compiled with this library. Google Chromium WebP contains a heap-based buffer overflow vulnerability that allows a remote attacker to perform an out-of-bounds memory write via a crafted HTML page. • https://github.com/alsaeroth/CVE-2023-4863-POC https://github.com/mistymntncop/CVE-2023-4863 https://github.com/LiveOverflow/webp-CVE-2023-4863 https://github.com/bbaranoff/CVE-2023-4863 https://github.com/talbeerysec/BAD-WEBP-CVE-2023-4863 https://github.com/huiwen-yayaya/CVE-2023-4863 https://github.com/CrackerCat/CVE-2023-4863- https://github.com/sarsaeroth/CVE-2023-4863-POC http://www.openwall.com/lists/oss-security/2023/09/21/4 http://www.openwall.com/list • CWE-122: Heap-based Buffer Overflow CWE-787: Out-of-bounds Write •
