CVE-2024-33601

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. The netgroup cache uses xmalloc/xrealloc and may terminate the process due to a memory allocation failure.

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.

It was discovered that GNU C Library nscd daemon contained a stack-based buffer overflow. A local attacker could use this to cause a denial of service. It was discovered that GNU C Library nscd daemon did not properly check the cache content, leading to a null pointer dereference vulnerability. A local attacker could use this to cause a denial of service.
