The remote host is missing an update to mutt announced via advisory DSA 1108-1. It was discovered that the mutt mail reader performs insufficient validation of values returned from an IMAP server, which might overflow a buffer and potentially lead to the injection of arbitrary code.

For the stable distribution (sarge) this problem has been fixed in version 1.5.9-2sarge2. For the unstable distribution (sid) this problem has been fixed in version 1.5.11+cvs20060403-2. We recommend that you upgrade your mutt package. https://secure1.securityspace.com/smysecure/catid.html?in=DSA%201108-1
