Summary: Updated poppler packages fix security vulnerabilities

Details: In Poppler 0.59.0, a floating point exception exists in the isImageInterpolationRequired() function in Splash.cc via a crafted PDF document. (CVE-2017-14518) In Poppler 0.59.0, a floating point exception occurs in the ImageStream class in Stream.cc, which may lead to a potential attack when handling malicious PDF files. (CVE-2017-14617) In Poppler 0.59.0, a NULL Pointer Dereference exists in AnnotRichMedia::Content::Content in Annot.cc via a crafted PDF document. (CVE-2017-14926) In Poppler 0.59.0, a NULL Pointer Dereference exists in AnnotRichMedia::Configuration::Configuration in Annot.cc via a crafted PDF document. (CVE-2017-14928) In Poppler 0.59.0, memory corruption occurs in a call to Object::dictLookup() in Object.h after a repeating series of Gfx::display, Gfx::go, Gfx::execOp, Gfx::opFill, Gfx::doPatternFill, Gfx::doTilingPatternFill and Gfx::drawForm calls (aka a Gfx.cc infinite loop), a different vulnerability than CVE-2017-14519. (CVE-2017-14929) The FoFiType1C::convertToType0 function in FoFiType1C.cc in Poppler 0.59.0 has a NULL pointer dereference vulnerability because a data structure is not initialized, which allows an attacker to launch a denial of service attack. (CVE-2017-14975) The FoFiTrueType::getCFFBlock function in FoFiTrueType.cc in Poppler 0.59.0 has a NULL pointer dereference vulnerability due to lack of validation of a table pointer, which allows an attacker to launch a denial of service attack.
