Package: stunnel4 Version: 3:4.29-1local1 Severity: normal

My Univ. recently updated their mail servers, and I could not read my mails anymore with Emacs/mew, that uses stunnel4 for encryption. It turned out the reason was, that the server responded with this string:

* OK [CAPABILITY STARTTLS CAPABILITY IMAP4 IMAP4rev1 ACL QUOTA LITERAL+ NAMESPACE UIDPLUS CHILDREN BINARY UNSELECT SORT LANGUAGE IDLE XSENDER X-NETSCAPE XSERVERINFO X-SUN-SORT X-SUN-IMAP X-ANNOTATEMORE X-UNAUTHENTICATE XUM1 AUTH=PLAIN AUTH=PLAIN] Messaging Multiplexor (Sun Java(tm) System Messaging Server 7.3-11.01 (built Sep 1 2009))

It turned out that this was way much longer than what stunnel4 expects. In common.h, one finds

#define STRLEN 256

When this is changed to

#define STRLEN 512

and the package recompiled, everything works well.

Perhaps the length of accepted strings should be increased? Or is this long a response against some standard?

All the best,

Harri K.
