An exploitable integer overflow vulnerability exists in the JPEG 2000 image parsing functionality of freedesktop.org Poppler 0.53.0. A specially crafted PDF file can lead to an integer overflow causing out of bounds memory overwrite on the heap resulting in potential arbitrary code execution. To trigger this vulnerability, a victim must open the malicious PDF in an application using this library.

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.

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.

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.

poppler through version 0.55.0 is vulnerable to an uncontrolled recursion in pdfunite resulting into potential denial-of-service.

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 since version 0.17.3 has been vulnerable to NULL pointer dereference in pdfunite triggered by specially crafted documents.

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.

Telegram Desktop 0.10.19 uses 0755 permissions for $HOME/.TelegramDesktop, which allows local users to obtain sensitive authentication information via standard filesystem operations.
