CVSS: 6.5EPSS: 0%CPEs: 11EXPL: 0CVE-2023-42669 – Samba: "rpcecho" development server allows denial of service via sleep() call on ad dc
https://notcve.org/view.php?id=CVE-2023-42669
A vulnerability was found in Samba's "rpcecho" development server, a non-Windows RPC server used to test Samba's DCE/RPC stack elements. This vulnerability stems from an RPC function that can be blocked indefinitely. The issue arises because the "rpcecho" service operates with only one worker in the main RPC task, allowing calls to the "rpcecho" server to be blocked for a specified time, causing service disruptions. This disruption is triggered by a "sleep()" call in the "dcesrv_echo_TestSleep()" function under specific conditions. Authenticated users or attackers can exploit this vulnerability to make calls to the "rpcecho" server, requesting it to block for a specified duration, effectively disrupting most services and leading to a complete denial of service on the AD DC. • https://access.redhat.com/errata/RHSA-2023:6209 https://access.redhat.com/errata/RHSA-2023:6744 https://access.redhat.com/errata/RHSA-2023:7371 https://access.redhat.com/errata/RHSA-2023:7408 https://access.redhat.com/errata/RHSA-2023:7464 https://access.redhat.com/errata/RHSA-2023:7467 https://access.redhat.com/security/cve/CVE-2023-42669 https://bugzilla.redhat.com/show_bug.cgi?id=2241884 https://bugzilla.samba.org/show_bug.cgi?id=15474 https://security.netapp.com& • CWE-400: Uncontrolled Resource Consumption •

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 •
