The GNU Mailutils are a collection of mail-related utilities, including an IMAP4 server (imap4d).

The imap4d server contains a format string bug in the handling of IMAP SEARCH requests.

An authenticated IMAP user could exploit the format string error in imap4d to execute arbitrary code as the imap4d user, which is usually root.

There are no known workarounds at this time.

All GNU Mailutils users should upgrade to the latest available version:

 # emerge --sync
 # emerge --ask --oneshot --verbose ">=net-mail/mailutils-0.6-r2"
