If you're a root user, listen up. Chainfire updated SuperSU to v1.69 as of last night, which fixes two exploits that could allow an attacker to leverage root privileges without first prompting the user. Probably nothing to get overly anxious about, but it's definitely a good idea to make sure you're running the latest. Details of these exploits will be released next Monday, so you'll want to grab the update before then.
Fortunately, this one's pretty easy – just install the update from the Play Store and you're covered; no need to flash anything.
This update also includes a handful of other fixes and things:
- XBIN mode (some new roots need this)
- Slightly adjusted binary installer
- Backup script installation now available for all backuptool-capable ROMs
- Fixed su-ing to a non-root user not working on some 4.3+ firmwares
- Fixed BOOTCLASSPATH vulnerability (CVE-2013-6774) - Fixed notification sanitization vulnerability (CVE-2013-6775) - Fixed possible closed special files vulnerability
- Updated language files
The update is already live in the Play Store, so make sure to pull it down as soon as you can.
