https://notcve.org/view.php?id=CVE-2024-33601
nscd: netgroup cache may terminate daemon on memory allocation failure The Name Service Cache Daemon's (nscd) netgroup cache uses xmalloc or xrealloc and these functions may terminate the process due to a memory allocation failure resulting in a denial of service to the clients. The flaw was introduced in glibc 2.15 when the cache was added to nscd. This vulnerability is only present in the nscd binary. nscd: la caché de netgroup puede terminar el daemon ante una falla en la asignación de memoria La caché de netgroup del daemon de caché del servicio de nombres (nscd) usa xmalloc o xrealloc y estas funciones pueden terminar el proceso debido a una falla en la asignación de memoria que resulta en una denegación de servicio a los clientes. La falla se introdujo en glibc 2.15 cuando se agregó el caché a nscd. Esta vulnerabilidad sólo está presente en el binario nscd. A flaw was found in the glibc netgroup cache. • http://www.openwall.com/lists/oss-security/2024/07/22/5 https://lists.debian.org/debian-lts-announce/2024/06/msg00026.html https://security.netapp.com/advisory/ntap-20240524-0014 https://sourceware.org/git/?p=glibc.git;a=blob;f=advisories/GLIBC-SA-2024-0007 https://access.redhat.com/security/cve/CVE-2024-33601 https://bugzilla.redhat.com/show_bug.cgi?id=2277205 • CWE-617: Reachable Assertion CWE-703: Improper Check or Handling of Exceptional Conditions •

https://notcve.org/view.php?id=CVE-2024-33602
nscd: netgroup cache assumes NSS callback uses in-buffer strings The Name Service Cache Daemon's (nscd) netgroup cache can corrupt memory when the NSS callback does not store all strings in the provided buffer. The flaw was introduced in glibc 2.15 when the cache was added to nscd. This vulnerability is only present in the nscd binary. nscd: la caché de netgroup supone que la devolución de llamada de NSS utiliza cadenas en el búfer La caché de netgroup del daemon de caché del servicio de nombres (nscd) puede dañar la memoria cuando la devolución de llamada de NSS no almacena todas las cadenas en el búfer proporcionado. La falla se introdujo en glibc 2.15 cuando se agregó el caché a nscd. Esta vulnerabilidad sólo está presente en el binario nscd. A flaw was found in the glibc netgroup cache.

nscd: Null pointer crashes after notfound response If the Name Service Cache Daemon's (nscd) cache fails to add a not-found netgroup response to the cache, the client request can result in a null pointer dereference. This flaw was introduced in glibc 2.15 when the cache was added to nscd. This vulnerability is only present in the nscd binary. nscd: el puntero nulo falla después de una respuesta no encontrada Si el caché del daemon de caché del servicio de nombres (nscd) no logra agregar una respuesta de grupo de red no encontrado al caché, la solicitud del cliente puede resultar en una desreferencia del puntero nulo.

nscd: Stack-based buffer overflow in netgroup cache If the Name Service Cache Daemon's (nscd) fixed size cache is exhausted by client requests then a subsequent client request for netgroup data may result in a stack-based buffer overflow. This flaw was introduced in glibc 2.15 when the cache was added to nscd. This vulnerability is only present in the nscd binary. nscd: desbordamiento de búfer en la región stack de la memoria en la caché de netgroup Si la caché de tamaño fijo del daemon de caché del servicio de nombres (nscd) se agota debido a las solicitudes de los clientes, una solicitud posterior del cliente de datos de netgroup puede provocar un desbordamiento del búfer basado en la pila.

CVSS: 8.8EPSS: 0%CPEs: 1EXPL: 4CVE-2024-2961 – glibc: Out of bounds write in iconv may lead to remote code execution
https://notcve.org/view.php?id=CVE-2024-2961
The iconv() function in the GNU C Library versions 2.39 and older may overflow the output buffer passed to it by up to 4 bytes when converting strings to the ISO-2022-CN-EXT character set, which may be used to crash an application or overwrite a neighbouring variable. La función iconv() en las versiones 2.39 y anteriores de la librería GNU C puede desbordar el búfer de salida que se le pasa hasta en 4 bytes al convertir cadenas al juego de caracteres ISO-2022-CN-EXT, lo que puede usarse para bloquear una aplicación. o sobrescribir una variable vecina. An out-of-bounds write flaw was found in the ISO-2022-CN-EXT plugin for glibc's iconv library. When converting from UCS4 charset, adding certain escape charterers is required to indicate where the charset was changed to the library. During this process, iconv improperly checks the boundaries of internal buffers, leading to a buffer overflow, which allows writing up to 3 bytes outside the desired memory location. • https://github.com/rvizx/CVE-2024-2961 https://github.com/tnishiox/cve-2024-2961 https://github.com/absolutedesignltd/iconvfix https://github.com/mattaperkins/FIX-CVE-2024-2961 http://www.openwall.com/lists/oss-security/2024/04/17/9 http://www.openwall.com/lists/oss-security/2024/04/18/4 http://www.openwall.com/lists/oss-security/2024/04/24/2 http://www.openwall.com/lists/oss-security/2024/05/27/1 http://www.openwall.com/lists/oss-security/2024/05/2 • CWE-787: Out-of-bounds Write •
