"Aleksandar Nikolic discovered that poppler incorrectly handled JPEG
2000 images. If a user or automated system were tricked into opening a
crafted PDF file, an attacker could cause a denial of service or
possibly execute arbitrary code with privileges of the user invoking
the program. (CVE-2017-2820)

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 JPEG 2000 images.
If a user or automated system were tricked into opening a crafted PDF
file, an attacker could cause cause poppler to crash, resulting in a
denial of service. (CVE-2017-9083)

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
