CVE-2019-11372

An out-of-bounds read in MediaInfoLib::File__Tags_Helper::Synched_Test in Tag/File__Tags.cpp in MediaInfoLib in MediaArea MediaInfo 18.12 leads to a crash.

CVE-2019-11373

An out-of-bounds read in File__Analyze::Get_L8 in File__Analyze_Buffer.cpp in MediaInfoLib in MediaArea MediaInfo 18.12 leads to a crash.

CVE-2020-15395

In MediaInfoLib in MediaArea MediaInfo 20.03, there is a stack-based buffer over-read in Streams_Fill_PerStream in Multiple/File_MpegPs.cpp (aka an off-by-one during MpegPs parsing).

CVE-2020-26797

Mediainfo before version 20.08 has a heap buffer overflow vulnerability via MediaInfoLib::File_Gxf::ChooseParser_ChannelGrouping.

For Debian 9 Stretch, these problems have been fixed in version 0.7.91-1+deb9u1.

We recommend that you upgrade your libmediainfo packages.
