The remote host is missing an update to newsx announced via advisory DSA 1622-1.

It was discovered that newsx, an NNTP news exchange utility, was affected by a buffer overflow allowing remote attackers to execute arbitrary code via a news article containing a large number of lines starting with a period. For the stable distribution (etch), this problem has been fixed in version 1.6-2etch1. For the testing (lenny) and unstable distribution (sid), this problem has been fixed in version 1.6-3. We recommend that you upgrade your newsx package.
