"Several vulnerabilities were discovered in djvulibre, a library and
set of tools to handle documents in the DjVu format. An attacker could
crash document viewers and possibly execute arbitrary code through
crafted DjVu files.

For Debian 9 stretch, these problems have been fixed in version
3.5.27.1-7+deb9u1.

We recommend that you upgrade your djvulibre packages.

For the detailed security status of djvulibre please refer to its
security tracker page at:
https://security-tracker.debian.org/tracker/djvulibre

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."
