binutils-gdb/binutils/configure.ac
Nick Clifton 7fac9594c4 In response to a public outcry the strings program now defaults to using the 
--all option which displays text from anywhere in the input file(s).  The
default used to be --data, which only displays text from loadable data sections,
but this requires the use of the BFD library.  Since the BFD library almost
certainly still contains buffer overrun and/or memory corruption bugs, and
since the strings program is often used to examine malicious code, it was
decided that the --data option option represents a possible security risk.

	* strings.c: Add new command line option --data to only scan the
	initialized, loadable data secions of binaries.  Choose the
	default behaviour of --all or --data based upon a configure
	option.
	* doc/binutils.texi (strings): Update documentation.  Include
	description  of why the --data option might be unsafe.
	* configure.ac: Add new option --disable-default-strings-all which
	restores the old behaviour of strings using --data by default.  If
	the option is not used make strings use --all by default.
	* NEWS: Mention the new behaviour of strings.
	* configure: Regenerate.
	* config.in: Regenerate.
