[Matroska-users] MKVToolNix v8.5.1 released

Hey,

I've released MKVToolNix v8.5.1 only four days after 8.5.0. The reason
is that Cisco's Talos Research Group has found several cases of
invalid memory access and instances of freeing memory twice in libEBML
(TALOS-CAN-0036, TALOS-CAN-0037). The consequences range from heap
information disclosure to denial of service.

Those issues have been fixed along with some more cases of invalid
memory access discovered while investigating the TALOS-CAN
reports. New releases of libEBML (v1.3.3) and libMatroska (v1.4.4)
were made yesterday[1]. Today's release of MKVToolNix incorporates
both updated libraries, and its build system requires at least those
versions if you want to use globally-installed copies.

As MKVToolNix and therefore both libEBML and libMatroska are often
used to process content from arbitrary sources I highly recommend
everyone to upgrade.

Here are the usual links:

…to the source code: http://www.bunkus.org/videotools/mkvtoolnix/source.html
…to the binaries: http://www.bunkus.org/videotools/mkvtoolnix/downloads.html

All binaries that I provide have been uploaded already.

Here's the full ChangeLog since the previous release:

----------------------------------------------------------------------
2015-10-21  Moritz Bunkus  <moritz at bunkus.org>

        * Released v8.5.1.

2015-10-20  Moritz Bunkus  <moritz at bunkus.org>

        * build system: libEBML v1.3.3 and libMatroska v1.4.4 are now
        required due to important fixes for invalid memory accesses in
        those two releases. The copies included in the MKVToolNix source
        code have been updated to those releases as well.

2015-10-19  Moritz Bunkus  <moritz at bunkus.org>

        * MKVToolNix GUI: bug fix: the "save file" dialogs did not have
        the currently entered file name pre-selected anymore. Fixes #1480.

        * MKVToolNix GUI: header editor enhancement: several track
        properties like name or language are shown as columns in the tree
        for easier distinction between tracks. They're also shown on the
        overview page on the right when that track's entry is selected in
        the tree. The text in the labels on this overview page can be
        selected with the mouse for copying & pasting elsewhere.

2015-10-18  Moritz Bunkus  <moritz at bunkus.org>

        * MKVToolNix GUI: bug fix: fixed a crash when loading corrupted
        job settings.

        * MKVToolNix GUI: header editor bug fix: the tree items weren't
        re-translated when the GUI language was changed.

        * mkvmerge: bug fix: updating the track headers wasn't working in
        some rare cases (corresponding error message "Re-rendering track
        headers: data_size != 0 not implemented yet").

2015-10-17  Moritz Bunkus  <moritz at bunkus.org>

        * MKVToolNix GUI: bug fix (Linux): the function "open folder" was
        inserting a superfluous leading slash in the directory name. This
        causes some file managers (in this particular case Dolphin on
        Linux) to interpret a directory name like "//home/mosu/…" as a
        share called "mosu" on a Samba/Windows server called "home" and to
        prepend the whole name with the "smb://" protocol. Fixes #1479.
----------------------------------------------------------------------

Have fun.

Kind regards,
mosu
