Description Arvid Requate

2017-04-19 13:56:00 CEST

Upstream Debian package version 0.13-4~deb8u1 fixes:

* Heap-buffer overflow due to Integer overflow in jbig2_image_new function (CVE-2016-9601)


libjbig2dec0 is maintained because ghostscript and okular depend on it. It has not been imported into ucs_4.2-0 yet, because jessie basically has the same package version as UCS 4.0.

Ok, ghostscript depends on libjbig2dec0, so I it was installed on my master by default and I've just updated.

* Package imported and built in errata4.2-0
* I've moved and updated the advisory to errata4.2-1
* Advisory content ok
* Package update ok
