There is a NULL pointer dereference in the AnnotPath::getCoordsLength function in Annot.h. A crafted input will lead to a remote denial of service attack.The FoFiType1C::cvtGlyph function in fofi/FoFiType1C.cc in Poppler allows remote attackers to cause a denial of service via a crafted PDF file, as demonstrated by pdftops.Poppler contains an out of bounds read vulnerability due to an incorrect memory access that is not mapped in its memory space, as demonstrated by pdfunite. This can result in memory corruption and denial of service. This may be exploitable when a victim opens a specially crafted PDF file.
