Google has published its latest monthly Android security bulletin, and released new factory and OTA images for supported Nexus and Pixel devices. The March 2017 update comes almost exactly one month after the February security patches were detailed.
Google says that all of the vulnerabilities disclosed in its latest bulletin were revealed to its partners on February 6, 2017 or earlier. "Security patch levels of March 05, 2017 or later address all of these issues," it added.
There are two separate security patch level strings in the new bulletin "to provide Android partners with the flexibility to more quickly fix a subset of vulnerabilities that are similar across all Android devices", Google explained. However, it also pointed out that "supported Google devices will receive a single OTA update with the March 05, 2017 security patch level".
That OTA update has begun to roll out today to Google devices; the latest OTA binary image files for supported Nexus and Pixel devices can be found here on Google"s site, and the new factory images are available here.
Details of the vulnerabilities and issues addressed in the latest security update follow below:
