"Wojciech Purczynski discovered that format string protection in
libsafe can be easily bypassed by using flag characters that are
implemented in glibc but are not implemented in libsafe. It was also
discovered that *printf function wrappers incorrectly parse argument
indexing in format strings, making some incorrect assumptions on the
number of arguments and conversion specifications.

These problems were fixed by the libsafe authors in 2.0-12."
