Security Bulletin: IBM MQ Appliance is affected by a libssh2 vulnerability (CVE-2019-17498)

Summary IBM MQ Appliance has resolved a libssh2 vulnerability. Vulnerability Details CVEID: CVE-2019-17498 DESCRIPTION: libssh2 is vulnerable to a denial of service, caused by an out-of-bounds read when connecting to a malicious SSH server that sends a disconnect message. A remote attacker could...

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.
