Detail

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.

Update instructions:

The problem can be corrected by updating your system to the following package versions:

Ubuntu 19.10:
libdjvulibre21 3.5.27.1-13ubuntu0.1

Ubuntu 19.04:
libdjvulibre21 3.5.27.1-10ubuntu0.1

Ubuntu 18.04 LTS:
libdjvulibre21 3.5.27.1-8ubuntu0.1

Ubuntu 16.04 LTS:
libdjvulibre21 3.5.27.1-5ubuntu0.1

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