Thanks.  What about this NEWS entry for it?

+  CVE-2009-5064: The ldd script would sometimes run the program under
+  examination directly, without preventing code execution through the
+  dynamic linker.  (The glibc project disputes that this is a security
+  vulnerability; only trusted binaries must be examined using the ldd
+  script.)

Thanks,
Florian
