Subject: Security ERRATA Low: openssh on SL6.x i386/x86_64
MIME-Version: 1.0

Synopsis: Low: openssh security, bug fix, and enhancement update
Advisory ID: SLSA-2013:1591-2
Issue Date: 2013-11-21
CVE Numbers: CVE-2010-5107
--

The default OpenSSH configuration made it easy for remote attackers to
exhaust unauthorized connection slots and prevent other users from being
able to log in to a system. This flaw has been addressed by enabling
random early connection drops by setting MaxStartups to 10:30:100 by
default. For more information, refer to the sshd_config(5) man page.
