Steve Kemp has reported a vulnerability in imapproxy, which
potentially can be exploited by malicious people to compromise a
vulnerable system.

capability line received from the IMAP server. This may be exploited
to execute arbitrary code via a specially crafted reply.

Successful exploitation requires that imapproxy is configured to
