ChangeLog (35416B)

 Fri Aug  7 09:30:00 AM CEST 2026
     Add sixteen plugins for a fast forensic/file-manager pass over large
     volumes, all of which parse headers directly and add no new
     dependency: pecoff (Windows PE/COFF executables, including the Rich
     header, the PDB path, the imphash and Authenticode common names),
     lnk (Windows shell links, including the volume serial, the
     originating machine name and the MAC address in the tracker block),
     sqlite (the 100-byte header only; the database is never opened, and
     WAL and rollback-journal sidecars are identified too), tar, iso9660,
     diskimage (QCOW2, VMDK, VHD and VHDX), heif (HEIC/HEIF/AVIF), webp,
     plist (binary and XML), id3 (with the Xing/Info and LAME encoder
     headers), gpx, kml, geotiff, mbox, apk (Android packages and Java
     archives) and ebook (EPUB and MOBI).  Only apk and ebook are
     conditional, on zlib, as they must inflate zip members.
     Add meta types 232-290 for the provenance these formats record:
     build, ownership, volume, database, geographic, mail and signing
     metadata.  Values are appended only, so this is source and binary
     compatible, but it raises EXTRACTOR_metatype_get_max(); the shared
     library version should be bumped (current++, age++) at the next
     release.
     Add fuzzing harnesses for all sixteen. -CG
 
 Fri Aug  7 03:40:00 AM CEST 2026
     Add video thumbnail and audio preview plugins, in a GStreamer and an
     FFmpeg (>= 5.1) variant each: thumbnailgst, thumbnailffmpeg,
     previewgst and previewopus.  The audio previews are Ogg Opus and are
     now reported with the MIME type "audio/ogg" rather than the
     "audio/opus" the plugin removed in 1.11 used, as the latter is not
     the type for Opus in an Ogg container (RFC 7845).
     Forget a channel on the plugin as well when the plugin process dies,
     instead of handing the next file to a freed struct EXTRACTOR_Channel;
     restart a plugin whose process is already gone when the next file is
     submitted, rather than skipping that file. -CG
 
 Thu Jul 30 11:14:02 PM CEST 2026
     Add new RTF and msoffice plugins.
     Fix interesting bugs and performance issues in ancient unzip logic.
     Fix offset calculation issue in WAV extractor.
     Minor memory leaks fixed in ELF extractor.
     Add support for OSSfuzz.
     Releasing GNU libextractor 1.19. -CG
 
 Tue Jul 28 11:14:02 PM CEST 2026
     Detect secure execution mode properly when deciding whether to
     honor LIBEXTRACTOR_PREFIX: use secure_getenv() where available,
     and otherwise fall back to issetugid() or to comparing the real
     against the effective UID/GID, instead of merely checking for
     root (#11609).
     Releasing GNU libextractor 1.18. -CG
 
 Sun Jul  5 10:55:57 PM CEST 2026
     Fixing various minor issues, including a missing 0 terminator
     in ZIP handling under particular circumstances.

     Fix some bit-flags set incorrectly for gzip-compressed headers.
     Security fix to not honor LIBEXTRACTOR_PREFIX in case we
     are linked into SUID binary and are running as root (which
     is anyway a bad idea, but we can be more conservative).
     Thanks to Haitam Lazaar for reporting.
     Releasing GNU libextractor 1.16. -CG
 
 Mon Jun 29 07:58:39 PM CEST 2026

 Fri Apr 28 16:18:26 PDT 2006
 	Fixing some i18n issues.  Specifically, EXTRACTOR_getKeywordTypeAsString
 	will now never return the translated version of the keyword type
 	(before, it *sometimes* returned the translated version, depending on
 	the default gettext domain and translation availability).  If translation
 	is desired, clients should use 'dgettext("libextractor", ret-value)' to
 	translate the returned value.

 	Some improvements for OpenBSD portability.

 Tue Sep 27 11:01:57 PDT 2005
 	Again better Mime-type detection for OLE2 streams.
 
 Mon Sep 26 20:44:10 PDT 2005
 	Minor improvements to the PDF extractor:
 	- first change is to avoid outputting keywords with empty values
   	  (for now the new check is only effective when the value is seen
 	  as a string of 8-bit characters; I'm not sure how to rewrite it
 	  for the Unicode case in the if branch just above.)
         - second change is to remap PDF Creator as 'software' keyword
           instead of 'creator'.

 	simpler and probably more robust.
 	Releasing libextractor 0.5.6.
 
 Fri Sep 16 16:41:04 PDT 2005
 	Made LE malloc file READ-ONLY.  This should help the VM conserve
 	memory, however this breaks the HTML extractor.

 Thu Sep 15 00:56:51 PDT 2005

 	(avoids need to do this, possibly repeatedly, in plugins and makes
 	sure that all plugins work with compressed files).  Eliminated gz
 	decompression from man and tar extractors.
 	Releasing libextractor 0.5.5.
 
 Sun Sep  4 02:08:56 PDT 2005
 	Changed code to export fewer symbols (refactoring plus linker options,

 Thu Jul 14 18:52:17 CEST 2005
 	Bugfixes in exiv2 extractor fixing remaining issues.
 	Changed plugins to not use filename but always only
 	rely on mmapped memory.  Extended API with function
 	that allows running getKeywords on data in memory
 	(instead of filename).  Extended API with encode
 	and decode functions for binary metadata.
 	Releasing libextractor 0.5.2.
 
 Mon Jul  4 18:10:14 CEST 2005
 	Preliminary integration of exiv2 support (not enabled

 	bindings into separate packages.
 	Releasing libextractor 0.5.1.
 
 Wed Jun 29 15:37:51 CEST 2005
 	Finally found out how to disable building static libs.
 	This should cut down compile time and installed size
 	by about a factor of 2 -- especially good since the
 	static version of the plugins is pretty, well, useless.
 
 Sat Jun 18 14:56:38 EST 2005
 	Fixed a score of compiler warnings and some minor bugs,
 	none of which should have been observable.

 Tue Sep 14 21:25:22 EST 2004
 	Improved performance of the HTML extractor by avoiding parsing
 	after the header (factor of 25 improvement for a 4 MB HTML file
 	resulting in a total improvement for total extraction time for
 	running all extractors of about 50%).  Improved performance
 	of the ZIP extractor for non-zip files by testing for the ZIP
 	header before trying to locate the central directory (for 5 MB
 	/dev/random time improves by a factor of about 15).  Same change
 	was also applied to the OO extractor (since OO is effectively a
 	zip).  Overall improvement for 5 MB /dev/random for running
 	all extractors is a factor of 10 (now takes 100ms on my machine
 	to run 720 times on the same 5 MB file passing that file as an
 	argument; the remaining time is pretty much doing 720x mmap and
 	related system calls).

 	libextractor is build with a couple of tiny additional
 	methods that are sufficient to build a Java class to
 	access libextractor.  The API is still incomplete but
 	already basically functional.  Releasing 0.3.0
 
 Sat Apr 10 01:34:04 EST 2004
