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:
https://security-tracker.debian.org/tracker/libmediainfo

NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
