The remote host is missing an update to skk, ddskk announced via advisory DSA 343-1.

https://secure1.securityspace.com/smysecure/catid.html?in=DSA%20343-1

skk (Simple Kana to Kanji conversion program), does not take appropriate security precautions when creating temporary files. This bug could potentially be exploited to overwrite arbitrary files with the privileges of the user running Emacs and skk. ddskk is derived from the same code, and contains the same bug. For the stable distribution (woody) this problem has been fixed in skk version 10.62a-4woody1 and ddskk version 11.6.rel.0-2woody1. For the unstable distribution (sid) this problem has been fixed in ddskk version 12.1.cvs.20030622-1, and skk will be fixed soon. We recommend that you update your skk and ddskk package-.
