CVE ID:	CVE-2019-16905
Description:	OpenSSH 7.7 through 7.9 and 8.x before 8.1, when compiled with an experimental key type, has a pre-authentication integer overflow if a client or server is configured to use a crafted XMSS key. This leads to memory corruption and local code execution because of an error in the XMSS key parsing algorithm. NOTE: the XMSS implementation is considered experimental in all released OpenSSH versions, and there is no supported way to enable it when building portable OpenSSH.
Test IDs:	1.3.6.1.4.1.25623.1.1.2.2020.1046   1.3.6.1.4.1.25623.1.0.108729   1.3.6.1.4.1.25623.1.1.2.2019.2294
