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).

The remote Ubuntu 16.04 ESM / 18.04 ESM / 20.04 ESM host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-5237-1 advisory.

    It was discovered that MediaInfoLib incorrectly handled certain specially crafted files. An attacker could     possibly use this issue to cause a denial of service. (CVE-2020-26797)

    It was discovered that MediaInfoLib incorrectly handled certain specially crafted MpegPs files. An     attacker could possibly use this issue to cause a denial of service. This issue only affected Ubuntu 18.04     ESM and Ubuntu 20.04 ESM. (CVE-2020-15395)

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

It was discovered that there were a number of vulnerabilities in libmediainfo, a library reading metadata such as track names, lengths, etc. from media files.

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

We recommend that you upgrade your libmediainfo packages.

For the detailed security status of libmediainfo please refer to its security tracker page at:
