Freedesktop poppler 0.74.0

Poppler 0.74.0 has a heap-based buffer over-read in the CairoRescaleBox.cc downsample_row_box_filter function.

A heap-based buffer underwrite exists in ImageStream::getLine() located at Stream.cc in Poppler 0.74.0 that can (for example) be triggered by sending a crafted PDF file to the pdfimages binary. It allows an attacker to cause Denial of Service (Segmentation fault) or possibly have unspecified other impact.

An issue was discovered in Poppler 0.74.0. A recursive function call, in JBIG2Stream::readGenericBitmap() located in JBIG2Stream.cc, can be triggered by sending a crafted pdf file to (for example) the pdfseparate binary. It allows an attacker to cause Denial of Service (Segmentation fault) or possibly have unspecified other impact. This is related to JArithmeticDecoder::decodeBit.

An issue was discovered in Poppler 0.74.0. There is a heap-based buffer over-read in the function Splash::blitTransparent at splash/Splash.cc.

An issue was discovered in Poppler 0.74.0. A recursive function call, in JBIG2Stream::readTextRegion() located in JBIG2Stream.cc, can be triggered by sending a crafted pdf file to (for example) the pdfimages binary. It allows an attacker to cause Denial of Service (Segmentation fault) or possibly have unspecified other impact. This is related to JBIG2Bitmap::clearToZero.

An issue was discovered in Poppler 0.74.0. There is a NULL pointer dereference in the function SplashClip::clipAALine at splash/SplashClip.cc.

An issue was discovered in Poppler 0.74.0. There is a heap-based buffer over-read in the function PSOutputDev::checkPageSlice at PSOutputDev.cc.

PDFDoc::markObject in PDFDoc.cc in Poppler 0.74.0 mishandles dict marking, leading to stack consumption in the function Dict::find() located at Dict.cc, which can (for example) be triggered by passing a crafted pdf file to the pdfunite binary.
