Name of the Vulnerable Software and Affected Versions libMatroska versions prior to 1.4.4

Description The issue allows context-dependent attackers to obtain sensitive information from process heap memory via crafted EBML lacing, which triggers an invalid memory access. This is due to a problem in the KaxInternalBlock::ReadData function.

Recommendations For versions prior to 1.4.4, update to version 1.4.4 or later to resolve the issue. As a temporary workaround, consider restricting access to the KaxInternalBlock::ReadData function until a patch is available.
