CVE-2017-6845

The PoDoFo::PdfColor::operator function in PdfColor.cpp in PoDoFo 0.9.4 allows remote attackers to cause a denial of service (NULL pointer dereference) via a crafted file.

These are all security issues fixed in the libpodofo-devel-0.9.7-2.2 package on the GA media of openSUSE Tumbleweed.

These are all security issues fixed in the libpodofo-0_10-devel-0.10.5-1.1 package on the GA media of openSUSE Tumbleweed.

This update for podofo fixes the following issues:
