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.
