mkvtoolnix:
https://www.bunkus.org/videotools/mkvtoolnix/doc/ChangeLog
libmatroska:
* build system: switched the build system from hand-crafted Makefiles to an autoconf/automake-based system. A pkg-config file will be installed as well; its name is »libmatroska«. Based on a similar patch for libEBML by Jan Engelhardt <jengelh at inai.de>.
* KaxBlock::ReadData(): fixed several instances of unchecked memory access leading to invalid memory access/segmentation faults with invalid or broken data inside block groups/simple blocks.
* KaxBlock::ReadInternalHead(): fixed a off-by-one buffer overflow if with EBML lacing and exactly one frame in the lace.
libebml:
* EbmlElement::Render(): doesn't catch exceptions anymore. Instead exceptions generated from the IOCallback class (e.g. if a write failed) are propagated to the caller.
* build system: switched the build system from hand-crafted Makefiles to an autoconf/automake-based system. A pkg-config file will be installed as well; its name is »libebml«. Patch by Jan Engelhardt <jengelh at inai.de>.
* EbmlMaster::Read(): when reading with SCOPE_ALL_DATA only those elements that could successfully be read will be kept (e.g. defective block groups will be dropped).
* EbmlMemoryStream: add a new class for safe memory access that throws exception on failures.
* EbmlMaster: Fixed read() trying to calculate the end position of elements with an unknown size. This avoids endless loops and assertions in certain cases. See https://trac.bunkus.org/ticket/1089
