USN-5606-1 fixed a vulnerability in poppler. Unfortunately it was missing a commit to fix it properly. This update provides the corresponding fix for Ubuntu 18.04 LTS and Ubuntu 16.04 ESM.
We apologize for the inconvenience.
Original advisory details:
It was discovered that poppler incorrectly handled certain PDF. An attacker could possibly use this issue to cause a denial of service or execute arbitrary code.
With Rapid7 live dashboards, I have a clear view of all the assets on my network, which ones can be exploited, and what I need to do in order to reduce the risk in my environment in real-time. No other tool gives us that kind of value and insight.
