Synopsis

Description

According to the version of the openssh packages installed, the EulerOS Virtualization installation on the remote host is affected by the following vulnerability :

 - Remotely observable behaviour in auth-gss2.c in OpenSSH through 7.8 could be used by remote attackers to detect existence of users on a target system when GSS2 is in use. NOTE: the discoverer states 'We understand that the OpenSSH developers do not want to treat such a username enumeration (or 'oracle') as a vulnerability.'(CVE-2018-15919)

Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
