CVE-2019-17498 – libssh2: integer overflow in SSH_MSG_DISCONNECT logic in packet.c
https://notcve.org/view.php?id=CVE-2019-17498
In libssh2 v1.9.0 and earlier versions, the SSH_MSG_DISCONNECT logic in packet.c has an integer overflow in a bounds check, enabling an attacker to specify an arbitrary (out-of-bounds) offset for a subsequent memory read. A crafted SSH server may be able to disclose sensitive information or cause a denial of service condition on the client system when a user connects to the server. En libssh2 versión v1.9.0 y anteriores, la lógica de la función SSH_MSG_DISCONNECT en el archivo packet.c presenta un desbordamiento de enteros en una comprobación de límites, lo que permite a un atacante especificar un desplazamiento arbitrario (fuera de límites) para una lectura de memoria posterior. Un servidor SSH diseñado puede ser capaz de revelar información confidencial o causar una condición de denegación de servicio en el sistema del cliente cuando un usuario conecta con el servidor. libssh2 version 1.9.0 contains a remotely trigger-able out-of-bounds read, leading to denial of service or potentially to information disclosure. • http://lists.opensuse.org/opensuse-security-announce/2019-11/msg00026.html http://packetstormsecurity.com/files/172835/libssh2-1.9.0-Out-Of-Bounds-Read.html https://blog.semmle.com/libssh2-integer-overflow-CVE-2019-17498 https://github.com/kevinbackhouse/SecurityExploits/tree/8cbdbbe6363510f7d9ceec685373da12e6fc752d/libssh2/out_of_bounds_read_disconnect_CVE-2019-17498 https://github.com/libssh2/libssh2/blob/42d37aa63129a1b2644bf6495198923534322d64/src/packet.c#L480 https://github.com/libssh2/libssh2/commit/dedcbd106f8e52d5586b0205bc7677e4c • CWE-190: Integer Overflow or Wraparound CWE-400: Uncontrolled Resource Consumption •
