The remote Gentoo host is missing one or more security-related
The remote host is affected by the vulnerability described in GLSA-200408-19
(courier-imap: Remote Format String Vulnerability)
There is a format string vulnerability in the auth_debug() function
which can be exploited remotely, potentially leading to arbitrary code
execution as the user running the IMAP daemon (oftentimes root). A
remote attacker may send username or password information containing
printf() format tokens (such as '%s'), which will crash the server or
cause it to execute arbitrary code.
This vulnerability can only be exploited if DEBUG_LOGIN is set to
something other than 0 in the imapd config file.
If DEBUG_LOGIN is enabled in the imapd configuration, a remote attacker
may execute arbitrary code as the root user.
Set the DEBUG_LOGIN option in /etc/courier-imap/imapd to 0. (This is
the default value.)
