It’s a relatively light month for Microsoft, with only six bulletins, and associated updates affecting Windows, Windows Server, Internet Explorer, Office, and the new Windows 10 browser Edge. Three of the bulletins are flagged as Critical. The bulletin summary has all the details, and it includes a link to Microsoft’s Security Advisories page for 2015, which may be of some interest.

Meanwhile, Adobe’s contribution to this month’s patch pile is more updates for Flash and Reader/Acrobat. The new version of Flash is 19.0.0.207, and it addresses thirteen vulnerabilities. The release notes get into the details of what was changed, which includes a few bug fixes unrelated to security. As always, Chrome will update itself and Internet Explorer on newer versions of Windows will get the new Flash via Windows Update.

The newest versions of Adobe Reader are 11.0.13 for Reader XI, and 2015.009.20069 for Acrobat Reader DC. At least fifty-six vulnerabilities are addressed in these updates. Check out the related security bulletin for additional information.
