CVE request: CouchDB insecure library loading (Debian/Ubuntu only)

I discovered that the /usr/bin/couchdb script on Debian/Ubuntu sets an insecure LD_LIBRARY_PATH environment variable, such that libraries from the current directory are loaded. If a local attacker placed a maliciously crafted shared library in a directory and an administrator were tricked into launching CouchDB from this directory, arbitrary code execution could be achieved. This vulnerability is only triggered when the /usr/bin/couchdb script is executed explicitly, since the init script (/etc/init.d/couchdb) changes the current directory before launching CouchDB. The vulnerability was introduced by Debian patch "mozjs1.9_ldlibpath.patch" on 3/24/2009. -Dan
