CVE-2019-7310: Canonical Ubuntu Linux

High severity, CVSS 7.8. EPSS: 2.1% chance of exploitation in the next 30 days.

In Poppler 0.73.0, 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, as demonstrated by pdftocairo.
