https://notcve.org/view.php?id=CVE-2019-17624
16 Oct 2019 — "" In X.Org X Server 1.20.4, there is a stack-based buffer overflow in the function XQueryKeymap. For example, by sending ct.c_char 1000 times, an attacker can cause a denial of service (application crash) or possibly have unspecified other impact. Note: It is disputed if the X.Org X Server is involved or if there is a stack overflow. En X.Org X Server versión 1.20.4, se presenta un desbordamiento de búfer en la región stack de la memoria en la función XQueryKeymap.
