The updated packages fix security vulnerabilities:

In DjVuLibre 3.5.27, DjVmDir.cpp in the DJVU reader component allows
attackers to cause a denial-of-service (application crash in
GStringRep::strdup in libdjvu/GString.cpp caused by a heap-based buffer
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
GBitmap::read_rle_raw infinite loop) by crafting a corrupted image file,
related to libdjvu/DjVmDir.cpp and libdjvu/GBitmap.cpp. (CVE-2019-15143)

In DjVuLibre 3.5.27, the sorting functionality (aka 
GArrayTemplate::sort) allows attackers to cause a denial-of-service
(application crash due to an Uncontrolled Recursion) by crafting a PBM
image file that is mishandled in libdjvu/GContainer.h. (CVE-2019-15144)

DjVuLibre 3.5.27 allows attackers to cause a denial-of-service attack
(application crash via an out-of-bounds read) by crafting a corrupted JB2
image file that is mishandled in JB2Dict::JB2Codec::get_direct_context in
libdjvu/JB2Image.h because of a missing zero-bytes check in
libdjvu/GBitmap.h. (CVE-2019-15145)

DjVuLibre 3.5.27 has a NULL pointer dereference in the function 
DJVU::filter_fv at IW44EncodeCodec.cpp. (CVE-2019-18804)
