gifsicle update

[Herbert Fortes <terberh@gmail.com>]

Hi,

Gifsicle just accepted security fix[0]. And there is
a backport in oldstable - 1.88-3~bpo8+1 - that I 
did in the past.

[0] - https://security-tracker.debian.org/tracker/source-package/gifsicle

I want to update the package. And so, I only need
to get the source which is in backport and put the patch
there. The debian /changelog will look like this:

+gifsicle (1.88-3~bpo8+2) jessie-backports; urgency=medium
+
+  * Closes: CVE-2017-1000421
+
+ -- Herbert Parentes Fortes Neto <hpfn@debian.org>  DATE
+
gifsicle (1.88-3~bpo8+1) jessie-backports; urgency=medium

  * Rebuild for jessie-backports.

Or I need to get the source from Jessie? If so, please
tell me how the debian/changelog entry needs to be. I
am worry about the version number.



Regards,
Herbert
