Updated jbigkit packages fix security vulnerability:

Florian Weimer found a stack-based buffer overflow flaw in the libjbig
library (part of jbigkit). A specially-crafted image file read by
libjbig could be used to cause a program linked to libjbig to crash
or, potentially, to execute arbitrary code (CVE-2013-6369).

The jbigkit package has been updated to version 2.1, which fixes
this issue, as well as a few other bugs, including the ability of
corrupted input data to force the jbig85 decoder into an end-less loop.
