Adobe Security Bulletin
Security updates available for Flash Player | APSB18-03
Summary
Adobe has released security updates for Adobe Flash Player for Windows,
Macintosh, Linux and Chrome OS. These updates address critical
vulnerabilities that could lead to remote code execution in Adobe Flash
Player 28.0.0.137 and earlier versions. Successful exploitation could
potentially allow an attacker to take control of the affected system.
Adobe is aware of a report that an exploit for CVE-2018-4878 exists in
the wild, and is being used in limited, targeted attacks against Windows
users. These attacks leverage Office documents with embedded malicious
Flash content distributed via email.
- audacity: GCC 6 wants std namespace, found via <cmath>.
- smpeg2: don't initialise unsigned with "0-1".
- libclucene/strigi: match GCC 6 (and 7, and 8, and 9.)
This change:
- properly enables dvdnav and dvdread support by passing
--enable-dvd{nav,read} via WAF_CONFIGURE_ARGS; they had both remained
disabled so far in spite of the inclusion of their buildlink3.mk files.
- adds a dependency on lcms2 to allow loading ICC profiles;
- bumps PKGREVISION.
LGTM leot@
1.3:
- Add support for avcC and hvcC structures
- Add support for LOAS AAC
- Improve support for RTP
- Use ISO 6937 as default DVB charset
- Ship pkg-config file
Sync player/lua/ytdl_hook.lua with upstream commit
2a0f9fc1588d8bda51a6340197c54285f3f62755 minus hunks that need `on_load_fail'
hook introduced after mpv-0.27.
Bump PKGREVISION.
### 1.12.4
The fourth 1.12 bug-fix release (1.12.4) was released on 7 December 2017.
This release only contains bugfixes and it should be safe to update from 1.12.x.
#### Major bugfixes in 1.12.4
- Dozens of fixes for various issues detected with the help of Google's OSS-Fuzz
project: https://github.com/google/oss-fuzz
Details to be found there in the bug tracker
- Performance regressions with registering debug categories after gst_init()
were fixed
- Regression with seeking back to 0 in souphttpsrc was fixed
- Regression with header rewriting in flacparse was fixed
- Regression with playbin/playsink leaking sinks was fixed
- Inconsistencies with DROPPED/HANDLED handling in pad probe handlers are fixed
- gst_bin_iterate_sorted() always returns sources last now, as documented
- gst_query_writable_structure() will never return NULL, for consistency with events
- Removal of metas from gst_buffer_meta_foreach() works correctly now
- OpenJPEG plugin builds with OpenJPEG >= 2.3
- CDIO plugin builds with CDIO >= 1.0
- gstreamer-vaapi works correctly with libva 1.0
- gst-libav was updated to ffmpeg 3.3.5
- Various fixes for memory leaks, deadlocks and crashes in all modules
- ... and many, many more!
2017-01-04 v1.7.0 "Mandarin Duck"
This release focused on high bit depth performance (10/12 bit) and vp9
encoding improvements.
- Upgrading:
This release is ABI incompatible due to new vp9 encoder features.
Frame parallel decoding for vp9 has been removed.
- Enhancements:
vp9 encoding supports additional threads with --row-mt. This can be greater
than the number of tiles.
Two new vp9 encoder options have been added:
--corpus-complexity
--tune-content=film
Additional tooling for respecting the vp9 "level" profiles has been added.
- Bug fixes:
A variety of fuzzing issues.
vp8 threading fix for ARM.
Codec control VP9_SET_SKIP_LOOP_FILTER fixed.
Reject invalid multi resolution configurations.
libdvdnav (6.0.0)
* fix crashes on some DVD on describe_title call
* fix various crashes related to PGC validity
* fix compilation issues
* fix API return codes
libdvdread (6.0.0)
* restrict the number of symbols to be exposed to the shared-object
* remove dvdinput_error function
* improve compatibility with some DVDs (notably the eOne ones)
* fix write after free in ifoFree functions
* fix possible buffer overflow in open
* additional checks on DVDReadBytes arguments
* fix leaks
Version 20.0.0 "I Am The Sun":
Important notes
* Feature removal: several deprecated features have been removed:
* mkvmerge: the deprecated options --identify-verbose (and its counterpart
-I), --identify-for-gui, --identify-for-mmg and
--identification-format verbose-text
* all command line tools: support for the deprecated, old, proprietary format
used for option files
* all command line tools: support for passing command line options via the
deprecated environment variables MKVTOOLNIX_OPTIONS, MKVEXTRACT_OPTIONS,
MKVINFO_OPTIONS, MKVMERGE_OPTIONS and MKVPROPEDIT_OPTIONS
* mkvinfo: most of its code was re-written in order to lay the groundwork for
including its functionality in MKVToolNix GUI but with more features than
the existing mkvinfo GUI. The result is that a lot of its output has been
changed slightly while keeping the basic layout. Changes include but aren't
limited to:
* Several element names are a bit clearer (e.g. Maximum cache instead of
MaxCache).
* All timestamps and durations are now output as nanoseconds in formatted
form (e.g. 01:23:45.67890123). All additional formats (e.g. floating
point numbers output in seconds or milliseconds) were removed.
* Element names for chapters and tags are now translated if a translation is
available.
* Elements located in wrong positions within the Matroska document are
handled better.
While mkvinfo's output is mostly kept very stable, it is not designed to be
parsed by other utilities. Even though I've tried hard to cram all changes
and cleanups into this version, additional changes may be made in the next
couple of releases depending on user feedback and bug reports.
New features and enhancements
* mkvmerge: AVC/h.264 packetizer (framed): access unit delimiter NALUs will
now be removed.
Bug fixes
* mkvmerge: AVC/h.264 parser: when fixing the bitstream timing information
mkvmerge will now use exact representations of the desired field duration if
possible. For example, when indicating 50 fields/second num_units_in_tick
is set to 1 and time_scale to 50 instead of 5368709 and 268435456.
* mkvmerge: AVC/h.264 parser: mkvmerge no longer assumes that encountering
sequence parameter set or picture parameter set NALUs signal the start of a
new frame.
* mkvmerge: AVC/h.264 packetizer (framed): when mkvmerge is told to fix the
bitstream timing information, it will now update all SPS NALUs, not just the
ones in the AVCC.
* mkvmerge: MPEG TS reader: TS packet payloads will only be treated as PES
packets if the payload actually starts with a PES start code. The prior
behavior led to wrong timestamps and potentially broken frame data.
* mkvmerge: MPEG TS reader: mkvmerge will now drop incomplete PES packets as
soon as an error is detected in the transport stream instead of passing the
incomplete frame to the packetizer. An error is assumed either if the
transport_error_indicator flag is set or if the value of the
continuity_counter header field doesn't match the expected value.
* mkvmerge: Opus: when re-muxing Opus from Matroska mkvmerge will now write
"block duration" elements for all block groups where a "discard padding" is
set, too.
* mkvmerge: SRT reader: mkvmerge can now handle SRT files with timestamps
without decimal places (e.g. 00:01:15 instead of 00:01:15.000).
* mkvmerge: read buffer I/O class: the class could get out of sync regarding
the file position of the underlying file I/O class causing wrong data to be
returned on subsequent read operations. One result was that trying to
identifying MPLS files that refer to very short M2TS files caused mkvmerge
to segfault.
* mkvmerge: multiplexer core: if there's a gap in audio timestamps, a new
block group/lace will be started for the first frame after each gap. Before
the fix the frame after the gap was often stored in the previous block group
causing the gap to be in the wrong place: at the end of that block
group.
* mkvextract: AVC/h.264: if two consecutive IDR frames with the same
idr_pic_id parameter and no access unit delimiters are found between them,
mkvextract will insert an access unit delimiter in order to signal the start
of a new access unit.
* MKVToolNix GUI: update check dialog: Markdown links will now be converted to
clickable links.
* build system: fixed a race condition when creating new directories if rake
is run with -jN in newer versions of Ruby/rake.
Build system changes
* [cmark](https://github.com/commonmark/cmark), the CommonMark parsing and
rendering library in C, is now required when building the GUIs.

Adobe Security Bulletin
Security updates available for Flash Player | APSB18-01
Summary
Adobe has released security updates for Adobe Flash Player for Windows,
Macintosh, Linux and Chrome OS. These updates address an important
out-of-bounds read vulnerability that could lead to information exposure.
The actual fix as been done by "pkglint -F */*/buildlink3.mk", and was
reviewed manually.
There are some .include lines that still are indented with zero spaces
although the surrounding .if is indented. This is existing practice.
Unsorted entries in PLIST files have generated a pkglint warning for at
least 12 years. Somewhat more recently, pkglint has learned to sort
PLIST files automatically. Since pkglint 5.4.23, the sorting is only
done in obvious, simple cases. These have been applied by running:
pkglint -Cnone,PLIST -Wnone,plist-sort -r -F
The actual cleanup has been done by pkglint:
* Added missing identifier comments
* Replaced ${PKGMANDIR} with a simple man, since the infrastructure does
all the magic for PLISTs
This release is mostly code refactoring as well as module inclusion.
Features:
Updates to multiple plugins (electrecetv, tvplayer, Teve2, cnnturk, kanald)
SOCKS module being included in the Streamlink installer (PySocks)

Version 18.0.0 "Apricity" 2017-11-18
New features and enhancements
* build system: when building with clang v3.8.0 or newer, `configure` will no
longer restrict optimization flags to `-O1` and use `-O3` again (older
versions of clang suffered from excessive memory usage with higher
optimization levels).
* build system: when building with mingw 7.2.0 or newer, `configure` will no
longer restrict optimization flags to `-O2` and use `-O3` again (older
versions of mingw suffered from bugs such as segmentation faults with higher
optimization levels).
* build system: stack protection is enabled when building with clang 3.5.0 or
newer on all platforms.
* mkvmerge: AVC & HEVC ES parsers: performance improvements by copying much
less memory around.
* mkvmerge: tags: reintroduced a workaround for non-compliant files with tags
that do not contain the mandatory `SimpleTag` element. This workaround was
removed during code refactoring in release v15.0.0.
* GUI: multiplexer: the "AAC is SBR/HE-AAC/AAC+" checkbox in the "audio
properties" section will be disabled if the functionality is not implemented
for the selected track's codec & container.
* GUI: multiplexer: the "reduce to core" checkbox in the "audio properties"
section will be disabled if the functionality is not implemented for the
selected track's codec.
Bug fixes
* mkvmerge: AAC ADTS parser: fixed interpretation of the
`channel_configuration` header element for ADTS files that do not contain a
program configuration element: value 7 means 7.1 channels.
* mkvmerge: Matroska identification: the `date_local` and `date_utc`
attributes will only be output if the identified Matroska file actually
contains the "date" header field.
* mkvmerge: WebVTT: mkvmerge did not recognize timestamp lines if the hours
components were absent.
* mkvpropedit, GUI's header editor: the `date` header field won't be added
automatically anymore whenever the segment info section is edited and the
`date` element is either deleted or not present in the first place.

Version 2.6
===========
New features
------------
1. x265 can now refine analysis from a previous HEVC encode (using options :option:`--refine-inter`, and :option:`--refine-intra`), or a previous AVC encode (using option :option:`--refine-mv-type`). The previous encode's information can be packaged using the *x265_analysis_data_t* data field available in the *x265_picture* object.
2. Basic support for segmented (or chunked) encoding added with :option:`--vbv-end` that can specify the status of CPB at the end of a segment. String this together with :option:`--vbv-init` to encode a title as chunks while maintaining VBV compliance!
3. :option:`--force-flush` can be used to trigger a premature flush of the encoder. This option is beneficial when input is known to be bursty, and may be at a rate slower than the encoder.
4. Experimental feature :option:`--lowpass-dct` that uses truncated DCT for transformation.
Encoder enhancements
--------------------
1. Slice-parallel mode gets a significant boost in performance, particularly in low-latency mode.
2. x265 now officially supported on VS2017.
3. x265 now supports all depths from mono0 to mono16 for Y4M format.
API changes
-----------
1. Options that modified PPS dynamically (:option:`--opt-qp-pps` and :option:`--opt-ref-list-length-pps`) are now disabled by default to enable users to save bits by not sending headers. If these options are enabled, headers have to be repeated for every GOP.
2. Rate-control and analysis parameters can dynamically be reconfigured simultaneously via the *x265_encoder_reconfig* API.
3. New API functions to extract intermediate information such as slice-type, scenecut information, reference frames, etc. are now available. This information may be beneficial to integrating applications that are attempting to perform content-adaptive encoding. Refer to documentation on *x265_get_slicetype_poc_and_scenecut*, and *x265_get_ref_frame_list* for more details and suggested usage.
4. A new API to pass supplemental CTU information to x265 to influence analysis decisions has been added. Refer to documentation on *x265_encoder_ctu_info* for more details.
Bug fixes
---------
1. Bug fixes when :option:`--slices` is used with VBV settings.
2. Minor memory leak fixed for HDR10+ builds, and default x265 when pools option is specified.
3. HDR10+ bug fix to remove dependence on poc counter to select meta-data information.
