The remote host is missing an update to couchdb announced via advisory DSA 2107-1.

Dan Rosenberg discovered that in couchdb, a distributed, fault-tolerant and schema-free document-oriented database, an insecure library search path is used a local attacker could execute arbitrary code by first dumping a maliciously crafted shared library in some directory, and then having an administrator run couchdb from this same directory. For the stable distribution (lenny), this problem has been fixed in version 0.8.0-2+lenny1. We recommend that you upgrade your couchdb package.
