Description Mark J. Cox (Product Security) 2008-03-04 07:16:58 EST
Whilst testing various format string exploits today, the security response team
 noticed that %n in a writable format string was not being captured by
FORTIFY_SOURCE=2 as we expected.  This was because the application was using
vasprintf, a function that hasn't been fortified.  Jakub confirmed this is true
and there is no fortification for asprintf, __asprintf, vasprintf, dprintf,
vdprintf, obstack_printf, obstack_vprint.

Can we get vasprintf fortified in time for F9 at a minimum?

Implemented in 2.7.90-8 and above.
