The remote host is missing an update to noffle announced via advisory DSA 244-1.

Dan Jacobson noticed a problem in noffle, an offline news server, that leads to a segmentation fault. It is not yet clear whether this problem is exploitable. However, if it is, a remote attacker could trigger arbitrary code execution under the user that calls noffle, probably news. For the stable distribution (woody) this problem has been fixed in version 1.0.1-1.1. The old stable distribution (potato) does not contain a noffle package. For the unstable distribution (sid) this problem has been fixed in version 1.1.2-1. We recommend that you upgrade your noffle package.
