cyrus-imapd - buffer overflow

Stefan Esser discovered several security related problems in the Cyrus
IMAP daemon. Due to a bug in the command parser it is possible to
access memory beyond the allocated buffer in two places which could
lead to the execution of arbitrary code.

For the stable distribution (woody) these problems have been fixed in
version 1.5.19-9.2

For the unstable distribution (sid) these problems have been fixed in
version 2.1.17-1.

We recommend that you upgrade your cyrus-imapd package immediately.
