CVE-2021-26843
https://notcve.org/view.php?id=CVE-2021-26843
An issue was discovered in sthttpd through 2.27.1. On systems where the strcpy function is implemented with memcpy, the de_dotdot function may cause a Denial-of-Service (daemon crash) due to overlapping memory ranges being passed to memcpy. This can triggered with an HTTP GET request for a crafted filename. NOTE: this is similar to CVE-2017-10671, but occurs in a different part of the de_dotdot function. Se ha detectado un problema en sthttpd versiones hasta 2.27.1. • https://github.com/blueness/sthttpd/issues/14 • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •
CVE-2017-10671
https://notcve.org/view.php?id=CVE-2017-10671
Heap-based Buffer Overflow in the de_dotdot function in libhttpd.c in sthttpd before 2.27.1 allows remote attackers to cause a denial of service (daemon crash) or possibly have unspecified other impact via a crafted filename. Un desbordamiento de búfer basado en memoria dinámica (heap) en la función de_dotdot en libhttpd.c en sthttpd 2.27.1 permite que atacantes remotos provoquen una denegación de servicio (cierre inesperado del demonio) o, posiblemente, provocar cualquier otro tipo de problema mediante un nombre de archivo manipulado. • http://www.openwall.com/lists/oss-security/2017/06/15/9 https://github.com/blueness/sthttpd/commit/c0dc63a49d8605649f1d8e4a96c9b468b0bff660 https://github.com/blueness/sthttpd/releases/tag/v2.27.1 • CWE-787: Out-of-bounds Write •
