The remote Gentoo host is missing one or more security-related
The remote host is affected by the vulnerability described in GLSA-200701-01
(DenyHosts: Denial of Service)
Tavis Ormandy of the Gentoo Linux Security Audit Team discovered that
DenyHosts used an incomplete regular expression to parse failed login
A remote unauthenticated attacker can add arbitrary hosts to the
blacklist by attempting to login with a specially crafted username. An
attacker may use this to prevent legitimate users from accessing a host
There is no known workaround at this time.

# emerge --ask --oneshot --verbose '>=app-admin/denyhosts-2.6'
Risk factor :
Medium / CVSS Base Score : 5.0
