The remote host is missing an update to mindi announced via advisory DSA 362-1.

https://secure1.securityspace.com/smysecure/catid.html?in=DSA%20362-1

mindi, a program for creating boot/root disks, 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 mindi. For the stable distribution (woody) this problem has been fixed in version 0.58.r5-1woody1. For the unstable distribution (sid) this problem will be fixed soon. Refer to Debian bug #203825. We recommend that you update your mindi package.
