We tend to support a product as long as the Vendor supports it and releases patches for it. I found this on the Adobe site: (Released 7/8/2015) Flash Player 184.108.40.2062 (172.62 MB)
It seems like Flash 13 is alive and kicking.
You could use the software distribution functionality to update Flash to later versions on all of your systems.
Our Software Distribution only has these listed versions listed as supported:
Adobe Flash 10.3.181.14
Adobe Flash 10.3.181.22
Adobe Flash Player 10.2.152.26
Adobe Flash Player 10.2.152.32
Adobe Flash Player 10.2.153.1 and Adobe AIR 2.6
Adobe Flash Player 10.2.159.1 and Adobe AIR 220.127.116.1140
Adobe Flash Player 10.3.181.16
Adobe Flash Player 10.3.181.26
Adobe Flash Player 10.3.181.34 & AdobeAIR 18.104.22.16830
Adobe Flash Player 10.3.183.7
Adobe Flash Player 22.214.171.124
Adobe Flash Player 9
So not seeing how to go from 13 to 18.
Edit: It looks like we already have the latest version of Flash in our data.
QAF1800209N – Flash Active X for IE 126.96.36.199
QNFP1800209N – Flash Plugin 188.8.131.52
Qnumbers that end with an N are Software Distribution type patches which will install the product if is it not already installed.
Try performing a Software Distribution scan against one of your machines that has Flash 13 installed on. Create a new Scan Template, don't filter anything and enable Software Distribution scanning. A link to the guide is in a previous post.
What product will this appear as? Adobe Flash 18 or Windows 7?
For the Flash Software Distribution type patches, they would be listed under OS's.
