CVSS: 7.8EPSS: 3%CPEs: 18EXPL: 18CVE-2023-4911 – GNU C Library Buffer Overflow Vulnerability
https://notcve.org/view.php?id=CVE-2023-4911
A buffer overflow was discovered in the GNU C Library's dynamic loader ld.so while processing the GLIBC_TUNABLES environment variable. This issue could allow a local attacker to use maliciously crafted GLIBC_TUNABLES environment variables when launching binaries with SUID permission to execute code with elevated privileges. Se descubrió un desbordamiento del búfer en el cargador dinámico ld.so de la librería GNU C mientras se procesaba la variable de entorno GLIBC_TUNABLES. Este problema podría permitir que un atacante local utilice variables de entorno GLIBC_TUNABLES manipuladas con fines malintencionados al iniciar archivos binarios con permiso SUID para ejecutar código con privilegios elevados. Dubbed Looney Tunables, Qualys discovered a buffer overflow vulnerability in the glibc dynamic loader's processing of the GLIBC_TUNABLES environment variable. • https://github.com/leesh3288/CVE-2023-4911 https://github.com/ruycr4ft/CVE-2023-4911 https://github.com/guffre/CVE-2023-4911 https://github.com/NishanthAnand21/CVE-2023-4911-PoC https://github.com/RickdeJager/CVE-2023-4911 https://github.com/hadrian3689/looney-tunables-CVE-2023-4911 https://github.com/Green-Avocado/CVE-2023-4911 https://github.com/xiaoQ1z/CVE-2023-4911 https://github.com/Diego-AltF4/CVE-2023-4911 https://github.com/KernelKrise/CVE-2023-4911 https:/&# • CWE-122: Heap-based Buffer Overflow CWE-787: Out-of-bounds Write •

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 •
