CVE-2016-1019

Adobe Flash Player Desktop Runtime

Adobe Flash Player 21.0.0.197 and earlier allows remote attackers to cause a denial of service (application crash) or possibly execute arbitrary code via unspecified vectors, as exploited in the wild in April 2016.

Exploitation status

CISA has confirmed this is being exploited in the wild. That is an observation of real attacks, not a prediction.
It is known to have been used in ransomware campaigns.
US federal civilian agencies are required to remediate it by 2022-03-24. That deadline does not bind private companies, but it is a reasonable benchmark for how urgently CISA views it.
A vendor advisory or patch reference has been published.

Required action

The impacted product is end-of-life and should be disconnected if still in use.

CISA’s wording, unedited.

What the metrics mean

It is reachable over a network, without needing local access.
For an attacker who can reach it, no special conditions are needed to exploit it.
To exploit it, no account is needed.
Beyond that, no action by a user is required.
