High Nessus Plugin ID 118809


The remote Fedora host is missing a security update.


# Version 28.2.0 'The Awakening' 2018-10-25

## Bug fixes

- mkvmerge, mkvinfo, mkvextract, mkvpropedit, MKVToolNix
GUI's info tool & chapter editor: fixed a case of memory
being accessed after it had been freed earlier. This can
be triggered by specially crafted Matroska files and
lead to arbitrary code execution. The vulnerability was
reported as Cisco TALOS 2018-0694 on 2018-10-25.

# Version 28.1.0 'Morning Child' 2018-10-23

## Bug fixes

- mkvmerge: AV1 parser: fixed an error in the sequence
header parser if neither the
`reduced_still_picture_header` nor the
`frame_id_numbers_present_flag` is set. Part of the fix
for #2410.

- mkvmerge: AV1 parser: when creating the `av1C` structure
for the Codec Private element the sequence header OBU
wasn't copied completely: its common data (type field &
OBU size among others) was missing. Part of the fix for

- mkvmerge: Matroska reader, AV1: mkvmerge will try to
re-create the `av1C` data stored in Codec Private when
reading AV1 from Matroska or WebM files created by
mkvmerge v28.0.0. Part of the fix for #2410.

- MKVToolNix GUI: info tool: the tool will no longer stop
scanning elements when an EBML Void element is found
after the first Cluster element. Fixes #2413.

# Version 28.0.0 'Voice In My Head' 2018-10-20

## New features and enhancements

- mkvmerge: AV1 parser: updated the code for the finalized
AV1 bitstream specification. Part of the implementation
of #2261.

- mkvmerge: AV1 packetizer: updated the code for the
finalized AV1-in-Matroska & WebM mapping specification.
Part of the implementation of #2261.

- mkvmerge: AV1 support: the `--engage enable_av1` option
has been removed again. Part of the implementation of

- mkvmerge: MP4 reader: added support for AV1. Part of the
implementation of #2261.

- mkvmerge: DTS: implemented dialog normalization gain
removal for extension substreams. Implements #2377.

- mkvmerge, mkvextract: simple text subtitles: added a
workaround for simple text subtitle tracks that don't
contain a duration. Implements #2397.

- mkvextract: added support for extracting AV1 to IVF.
Part of the implementation of #2261.

- mkvextract: IVF extractor (AV1, VP8, VP9): precise
values will be used for the frame rate numerator &
denominator header fields for certain well-known values
of the track's default duration.

- mkvmerge: VP9: mkvmerge will now create codec private
data according to the VP9 codec mapping described in the
WebM specifications. Implements #2379.

- MKVToolNix GUI: automatic scaling for high DPI displays
is activated if the GUI is compiled with Qt ≥ 5.6.0.
Fixes #1996 and #2383.

- MKVToolNix GUI: added a menu item ('Help' → 'System
information') for displaying information about the
system MKVToolNix is running on in order to make
debugging easier.

- MKVToolNix GUI: multiplexer, header editor: the user can
enter a list of predefined track names in the
preferences. She can later select from them in 'track
name' combo box. Implements #2230.

## Bug fixes

- mkvmerge: JSON identification: fixed a bug when removing
invalid UTF-8 data from strings before they're output as
JSON. Fixes #2398.

- mkvmerge: MP4/QuickTime reader: fixed handling of PCM
audio with FourCC `in24`. Fixes #2391.

- mkvmerge: MPEG transport stream reader, teletext
subtitles: the decision whether or not to keep frames
around in order to potentially merge them with the
following frame is made sooner. That avoids problems if
there are large gaps between teletext subtitle frames
which could lead to frames being interleaved too late.
Fixes #2393.

- mkvextract: IVF extractor (AV1, VP8, VP8): the frame
rate header fields weren't clamped to 16 bits properly
causing wrong frame rates to be written in certain

- mkvpropedit, MKVToolNix GUI's header editor: fixed file
corruption when a one-byte space must be covered with a
new EBML void element but all surrounding elements have
a 'size length' field that's eight bytes long already.
Fixes #2406.

Note that Tenable Network Security has extracted the preceding
description block directly from the Fedora update system website.
Tenable has attempted to automatically clean and format it as much as
possible without introducing additional issues.
