Versie 8.5.1 van MKVToolNix is uitgekomen. Met deze verzameling opensourceprogramma's kunnen Matroska-bestanden worden bekeken, bewerkt en geconverteerd. Zo kunnen geluidssporen en ondertiteling worden toegevoegd, verwijderd of juist als standaard worden ingesteld. Het zijn afzonderlijke commandline-tools, maar er wordt ook een grafische gebruikersinterface meegeleverd. Deze is in versie 8.0 vervangen door een nieuwe. De oude kon nog wel worden gebruikt, maar is sinds versie 8.4.0 helemaal verwijderd. Versies kunnen worden gedownload voor Windows, een groot aantal Linux-distributies en OS X. In deze uitgave zijn verschillende fouten verholpen en worden er nieuwe versies van libEBML en libMatroska meegeleverd.
MKVToolNix v8.5.1 released
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. 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’s the full ChangeLog since the previous release:
- 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.
- 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.
- 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").
- 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.
