A security issue affects these releases of Ubuntu and its derivatives:

Summary

Several security issues were fixed in DjVuLibre.

Software Description

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.
