https://notcve.org/view.php?id=CVE-2019-3855
An integer overflow flaw which could lead to an out of bounds write was discovered in libssh2 before 1.8.1 in the way packets are read from the server. A remote attacker who compromises a SSH server may be able to execute code on the client system when a user connects to the server. Se ha descubierto un error de desbordamiento de enteros que podría conducir a una escritura fuera de límites en libssh2, en versiones anteriores a la 1.8.1, en la forma en la que los paquetes se leen desde el servidor.
