The remote host is missing an update to catdoc announced via advisory DSA 575-1.

A temporary file problem has been discovered in xlsview from the catdoc suite, convertors from Word to TeX and plain text, which could lead to local users being able to overwrite arbitrary files via a symlink attack on predictable temporary file names. For the stable distribution (woody) this problem has been fixed in version 0.91.5-1.woody3. For the unstable distribution (sid) this problem has been fixed in version 0.91.5-2. We recommend that you upgrade your catdoc package.
