Samsung
promised in December that it would address a serious security hole in some of
its smartphones and tablets running Exynos processors "as quickly as possible," and it looks like the
company has begun that process. T-Mobile has released an over-the-air update
today to its Galaxy Note II customers that offers "Exynos and other
security enhancements." In addition, Sprint has released its own
over-the-air update for the Galaxy S II Epic 4G Touch with unspecified "security
updates" that are said to address the Exynos exploit.
The security
hole was first discovered in mid-December, when xda-developers
users found that malicious apps could gain root access to certain devices on
their own accord, leaving user data and other primary phone functions
vulnerable. Samsung previously released an update to Galaxy S III devices in the UK
to fix the exploit, but multiple models including the international Galaxy S II, Galaxy Note, and Galaxy Note II remain exposed at this time. The good news is
that users will remain safe so long as they limit themselves to downloading
popular and well-known applications.
Update: Article modified to clarify that Samsung
patched some UK Galaxy S III's earlier this month. [TheVerge]
