========================================================================== Ubuntu Security Notice USN-4957-2 May 18, 2021
djvulibre vulnerabilities ==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 16.04 ESM
Summary:
Several security issues were fixed in DjVuLibre.
Software Description: - djvulibre: DjVu image format library and tools
Details:
USN-4957-1 fixed several vulnerabilities in DjVuLibre. This update provides the corresponding update for Ubuntu 16.04 ESM.
Original advisory 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 16.04 ESM: libdjvulibre21 3.5.27.1-5ubuntu0.1+esm1
After a standard system update you need to reboot your computer to make all the necessary changes.
