gnu/packages/patches/mutt-CVE-2014-9116.patch

-Fix CVE-2014-9116.  Copied from Debian:
-
-This patch solves the issue raised by CVE-2014-9116 in bug 771125.
-
-We correctly redefine what are the whitespace characters as per RFC5322; by
-doing so we prevent mutt_substrdup from being used in a way that could lead to
-a segfault.
-
-The lib.c part was written by Antonio Radici <antonio@debian.org> to prevent
-crashes due to this kind of bugs from happening again.
-
-The wheezy version of this patch is slightly different, therefore this patch
-has -jessie prefixed in its name.
-
-The sendlib.c part was provided by Salvatore Bonaccorso and it is the same as
-the upstream patch reported here:
-http://dev.mutt.org/trac/attachment/ticket/3716/ticket-3716-stable.patch
