The function GfxImageColorMap::getGray in GfxState.cc in Poppler 0.54.0 allows remote attackers to cause a denial of service (stack-based buffer over-read and application crash) via a crafted PDF document, related to missing color-map validation in ImageOutputDev.cc.
Stack buffer overflow in GfxState.cc in pdftocairo in Poppler before 0.56 allows remote attackers to cause a denial of service (application crash) via a crafted PDF document.
Integer overflow leading to Heap buffer overflow in JBIG2Stream.cc in pdftocairo in Poppler before 0.56 allows remote attackers to cause a denial of service (application crash) or possibly have unspecified other impact via a crafted PDF document.
In Poppler 0.54.0, a memory leak vulnerability was found in the function gmalloc in gmem.cc, which allows attackers to cause a denial of service via a crafted file.
In Poppler 0.54.0, a memory leak vulnerability was found in the function Object::initArray in Object.cc, which allows attackers to cause a denial of service via a crafted file.
poppler 0.54.0, as used in Evince and other products, has a NULL pointer dereference in the JPXStream::readUByte function in JPXStream.cc. For example, the perf_test utility will crash (segmentation fault) when parsing an invalid PDF file.
Integer overflow in the vrend_create_shader function in vrend_renderer.c in virglrenderer before 0.6.0 allows local guest OS users to cause a denial of service (process crash) via crafted pkt_length and offlen values, which trigger an out-of-bounds access.
pkexec, when used with --user nonpriv, allows local users to escape to the parent session via a crafted TIOCSTI ioctl call, which pushes characters to the terminal's input buffer.
