USN-4198-1: DjVuLibre vulnerabilities

Releases

• Ubuntu 19.10
• Ubuntu 19.04
• Ubuntu 18.04 ESM
• Ubuntu 16.04 ESM

Packages

• 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

• libdjvulibre21 - 3.5.27.1-8ubuntu0.1

Ubuntu 16.04

• libdjvulibre21 - 3.5.27.1-5ubuntu0.1

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