The remote host is missing an update to afuse announced via advisory DSA 1611-1.

https://secure1.securityspace.com/smysecure/catid.html?in=DSA%201611-1

Anders Kaseorg discovered that afuse, an automounting file system in user-space, did not properly escape meta characters in paths. This allowed a local attacker with read access to the filesystem to execute commands as the owner of the filesystem. For the stable distribution (etch), this problem has been fixed in version 0.1.1-1+etch1. For the unstable distribution (sid), this problem has been fixed in version 0.2-3. We recommend that you upgrade your afuse (0.1.1-1+etch1) package.
