Adobe Reader X for Windows
Sequential update (from 10.1.x) to 10.1.3 http://www.adobe.com/support/downloads/detail.jsp?ftpID=5358
for details of this update: http://helpx.adobe.com/content/dam/help/attachments/Acrobat_Reader_ReleaseNote_10.1.3.pdf
For what it's worth: Today's Adobe Reader updates its included version of Flash Player ( authplay.dll ) to version 10.3.183.18. As we are aware, the latest series/version of Flash is 184.108.40.206. For whatever reason, it seems that some people can't (or don't want to??) upgrade Flash from the older 10.x series to the newer 11.x series, and as such, Adobe doesn't want to force the issue... I've found the following statement in Adobe Security Bulletin apsb12-07:
"For users who cannot update to Flash Player 220.127.116.11, Adobe has developed a patched version of Flash Player 10.3, Flash Player 10.3.183.18"
[See the second paragraph under SOLUTION http://www.adobe.com/support/security/bulletins/apsb12-07.html ]
This bug fix release addresses several issues that were reported shortly after the release of version 3.66.
