Vulnerability Insight:
The updated packages fix security vulnerabilities:
In DjVuLibre 3.5.27, DjVmDir.cpp in the DJVU reader component allows

over-read) by crafting a DJVU file. (CVE-2019-15142)
In DjVuLibre 3.5.27, the bitmap reader component allows attackers to
cause a denial-of-service error (resource exhaustion caused by a
