Leave it to hackers to fix a serious issue made by a manufacturer. I’m sure all of you have heard of the Exynos security bug by now. It’s a kernel vulnerability that could let any app easily gain root access. Obviously, it’s extremely unsafe to be walking around with a device open to any malicious code, and all Exynos 4 devices are affected (Galaxy S II, international S III, Note, Note II, and more).
Of course, while Samsung is working on it, the people at CyanogenMod have already fixed it. They are releasing CyanogenMod 10.1 nightlies with the bug completely fixed, and are working on integrating the patch into older builds (like CM10 and CM9). Hopefully this patch can be used in other custom ROMs. But for those of you who don’t have custom ROMs, just don’t download suspicious apps. Always make sure your apps are legitimate, and only download from trusted sources.
