Google has posted the details for the "Android Security Bulletin Monthly Release" for November, 2015 at the new Android Security Updates Google Group.

Partners have had these details since October 5 (or earlier) and the patches will be hitting regular AOSP during the next 48 hours. Supported Nexus devices will have an OTA update already rolling out to get them patched and current, and new factory images will also be posted to the Google Developer's site.

Google also states the "most severe of these issues is a Critical security vulnerability that could enable remote code execution on an affected device through multiple methods such as email, web browsing, and MMS when processing media files," though there have been no reports of any exploitation of any of the current issues.

For all the details about what was patched, and who to credit for finding these issues, see the link below.
