            Bug ID: 3705
           Summary: Disk space exhaustion from PerSourcePenalties logging
           Product: Portable OpenSSH
           Version: -current
          Hardware: amd64
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P5
         Component: sshd
          Assignee: unassigned-bugs at mindrot.org
          Reporter: jtesta at positronsecurity.com

As mentioned in
https://lists.mindrot.org/pipermail/openssh-unix-dev/2024-June/041416.html,
the logging related to PerSourcePenalties
(https://github.com/openssh/openssh-portable/blob/V_9_8/sshd.c#L606)
was observed to output 73MB per minute when a very high rate of
connection flooding is performed.  This occurs using default options.

Perhaps the non-default SYSLOG_LEVEL_VERBOSE level should be used
instead.
