CVE-2015-4902 Oracle Java SE: software flaw

In plain words: A mistake in the software that attackers have found a way to abuse. Depends on the product — see the description and the vendor advisory.

Confirmed exploited by CISA on Mar 3, 2022 · US federal patch deadline Mar 24, 2022

What to do

Install Oracle's security update for Java SE. If no update exists, follow the vendor's workaround or stop using the product until one ships.
Turn on automatic updates for the operating system and for Office, PDF and archive apps.
Be careful with unexpected attachments — documents, .zip/.rar files and shortcuts are common bait.
Use a normal (non-admin) account day to day and keep built-in protection like Microsoft Defender on.

Who is affected

Could reach you. This one is aimed at devices or apps of the kind people own.
