MKVToolNix v8.5.1 released
Wednesday 21 October 2015 @ 10:47 am

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.

You can download the source code or one of the binaries.

Here’s the full ChangeLog since the previous release:

Have fun.

MKVToolNix v8.5.0 released

I’ve released MKVToolNix v8.5.0. It contains the usual mix of bug fixes and enhancements, most of them for the GUI but some for mkvmerge, too. Most of these correspond directly to entries in the issue tracker.

There’s one small change for package maintainers: there’s a new translation of the man pages into Catalan.

You can download the source code or one of the binaries.

Have fun.
