The remote host is missing an update to cscope announced via advisory DSA 1806-1.

Matt Murphy discovered that cscope, a source code browsing tool, does not verify the length of file names sourced in include statements, which may potentially lead to the execution of arbitrary code through specially crafted source code files. For the stable distribution (lenny), this problem has been fixed in version 15.6-6+lenny1. Due to a technical limitation in the Debian archive management scripts the update for the old stable distribution (etch) cannot be released synchronously. It will be fixed in version 15.6-2+etch1 soon. For the unstable distribution (sid), this problem will be fixed soon. We recommend that you upgrade your cscope package.
