The remote host is missing an update to mime-support announced via advisory DSA 292-1.

Colin Phipps discovered several problems in mime-support, that contains support programs for the MIME control files 'mime.types' and 'mailcap'. When a temporary file is to be used it is created insecurely, allowing an attacker to overwrite arbitrary under the user id of the person executing run-mailcap, most probably root. Additionally the program did not properly escape shell escape characters when executing a command. This is unlikely to be exploitable, though. For the stable distribution (woody) these problems have been fixed in version 3.18-1.1. For the old stable distribution (potato) these problems have been fixed in version 3.9-1.1. For the unstable distribution (sid) these problems have been fixed in version 3.22-1. We recommend that you upgrade your mime-support packages.
