CVE-2017-9776

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.

Jiaqi Peng discovered that the poppler pdfunite tool incorrectly parsed certain malformed PDF documents. If a user or automated system were tricked into opening a crafted PDF file, an attacker could cause poppler to crash, resulting in a denial of service (CVE-2017-7511).

It was discovered that the poppler pdfunite tool incorrectly parsed certain malformed PDF documents. If a user or automated system were tricked into opening a crafted PDF file, an attacker could cause poppler to hang, resulting in a denial of service (CVE-2017-7515).

It was discovered that poppler incorrectly handled memory when processing PDF documents. If a user or automated system were tricked into opening a crafted PDF file, an attacker could cause poppler to consume resources, resulting in a denial of service (CVE-2017-9406, CVE-2017-9408).

Alberto Garcia, Francisco Oca, and Suleman Ali discovered that the poppler pdftocairo tool incorrectly parsed certain malformed PDF documents. If a user or automated system were tricked into opening a crafted PDF file, an attacker could cause poppler to crash, resulting in a denial of service (CVE-2017-9775).

Integer overflow leading to Heap buffer overflow in JBIG2Stream.cc in pdftocairo in Poppler allows attackers to cause a denial of service (application crash) or possibly have unspecified other impact via a crafted PDF document (CVE-2017-9776).

The function GfxImageColorMap::getGray in GfxState.cc in Poppler allows 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 (CVE-2017-9865).
