No vendor fix yet — apply a workaround or compensating control (WAF / firewall / segmentation) and watch for a patch.

The KaxInternalBlock::ReadData function in libMatroska before 1.4.4 allows context-dependent attackers to obtain sensitive information from process heap memory via crafted EBML lacing, which triggers an invalid memory access.
