CVE-2018-19058

A reachable abort in Object.h will lead to denial-of-service because EmbFile::save2 in FileSpec.cc lacks a stream check before saving an embedded file.

CVE-2018-20481

Poppler mishandles unallocated XRef entries, which allows remote attackers to cause a denial-of-service (NULL pointer dereference) via a crafted PDF document.

CVE-2018-20662

Poppler allows attackers to cause a denial-of-service (application crash and segmentation fault by crafting a PDF file in which an xref data structure is corrupted.

CVE-2019-7310

A heap-based buffer over-read (due to an integer signedness error in the XRef::getEntry function in XRef.cc) allows remote attackers to cause a denial of service (application crash) or possibly have unspecified other impact via a crafted PDF document.

CVE-2019-9200

A heap-based buffer underwrite exists in ImageStream::getLine() located at Stream.cc 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.

For Debian 8 Jessie, these problems have been fixed in version 0.26.5-2+deb8u8.

We recommend that you upgrade your poppler packages.
