djvulibre vulnerabilities
==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
– Ubuntu 19.10
– Ubuntu 19.04
– Ubuntu 18.04 LTS
– Ubuntu 16.04 LTS
Summary:
Several security issues were fixed in DjVuLibre.
Software Description:
– djvulibre: DjVu image format library and tools
Details:
It was discovered that DjVuLibre incorrectly handled certain memory
operations. If a user or automated system were tricked into processing a
specially crafted DjVu file, a remote attacker could cause applications
to hang or crash, resulting in a denial of service, or possibly execute
arbitrary code.

The problem can be corrected by updating your system to the following
package versions:
Ubuntu 19.10:
libdjvulibre21 3.5.27.1-13ubuntu0.1

After a standard system update you need to reboot your computer to make
all the necessary changes.
