The patch fixes 30 vulnerabilities, 10 rated a critical severity, 15 high risk, and 5 medium severity. Affected Android iterations range from version 4.4.4 to 8.0, but only some vulnerabilities impact all platform releases.

The most affected component was media framework, with 24 vulnerabilities addressed in it, including 10 rated critical severity, all remote code execution flaws. 10 other bugs were rated high risk, including one remote code execution, 4 elevation of privilege, and 5 denial of service issues.

The remaining 4 bugs are moderate risk. Three of them, however, have a medium risk rating only when affecting Android versions 7.0, 7.1.1, 7.1.2, or 8.0. When impacting platform releases older than 7.0, they are considered high severity, Google said in an advisory.

Google also addressed a high risk elevation of privilege flaw in Framework, three high risk (2 remote code execution and one elevation of privilege) issues in Libraries, one high severity denial of service bug in Runtime, and one moderate elevation of privilege bug in System.
