file-4.20 is now available

[Christos Zoulas]

New in this release is a BNF file that shows the syntax of magic
files.  Many more checks have been added to the magic parser and
badly formatted magic entries have been fixed. There is now a
"default" statement in the magic entires. Finally a exploitable
flaw in the print buffer management has been fixed. The ChangeLog
is appended and you can download it from:

	* fix integer underflow in file_printf which can lead to
	  to exploitable heap overflow (Jean-Sebastien Guay-Lero)

	* make socket/pipe reading more robust

	* Centralize all the tests in file_buffer.

	* Add exclude flag.

	* Move the "type" detection code from parse() into its own table
	  driven routine.  This avoids maintaining multiple lists in
	  file.h.

	* Add an optional conditional field (ust before the type field).
	  This code is wrapped in "#ifdef ENABLE_CONDITIONALS" as it is
	  likely to go away.

	* Fix an initialization bug in check_mem().

	* Add a "default" type to print a message if nothing previously
	  matched at that level or since the last default at that
	  level.  This is useful for setting up switch-like statements.
	  It can also be used to do if/else constructions without a
	  redundant second test.

	* Fix the "x" special case test so that one can test for that
	  string with "=x".

	* Allow "search" to search the entire buffer if the "/N"
	  search count is missing.

	* Make "regex" work!  It now starts its search at the
	  specified offset and takes an (optional) "/N" line count to
	  specify the search range; otherwise it searches to the end
	  of the file.  The match is now grabbed correctly for format
	  strings and the offset set to the end of the match.

	* Add a "/s" flag to "regex" and "search" to set the offset to
	  the start of the match.  By default the offset is set to the
	  end of the match, as it is with other tests.  This is mostly
	  useful for "regex".

	* Make "search", "string" and "pstring" use the same
	  file_strncmp() routine so that they support the same flags;
	  "bestring16" and "lestring16" call the same routine, but
	  with flags = 0.  Also add a "/C" flag (in analogy to "/c")
	  to ignore the case on uppercase (lowercase) characters in
	  the test string.

	* Strict adherence to C style string escapes.  A warnings are
	  printed when compiling.  Note: previously "\a" was
	  incorrectly translated to 'a' instead of an <alert> (i.e.,
	  BELL, typically 0x07).

	* Make this compile with "-Wall -Wextra" and all the warning
	  flags used with WARNS=4 in the NetBSD source.  Also make it
	  pass lint.

	* Many "cleanups" and hopefully not too many new bugs!

	* make several more files compile with gcc warnings
	  on and also make them pass lint.

2007-01-16 14:54 Anon Ymous <do at not.spam.me>

	* fix a puts()/putc() usage goof in file.c

	* make file.c compile with gcc warnings and pass lint
