Description

The remote host is affected by the vulnerability described in GLSA-200704-18 (Courier-IMAP: Remote execution of arbitrary code)

 CJ Kucera has discovered that some Courier-IMAP scripts don't properly handle the XMAILDIR variable, allowing for shell command injection.
 Impact :

 A remote attacker could send specially crafted login credentials to a Courier-IMAP server instance, possibly leading to remote code execution with root privileges.
 Workaround :

 # emerge --sync # emerge --ask --oneshot --verbose '>=net-mail/courier-imap-4.0.6-r2'
