Samsung Exynos 4-based processors vulnerable to serious
Devices running Samsung's Exynos 4-based processors (4210 and 4412) including the Galaxy S III and Galaxy Note II have been shown to be vulnerable to a hack with potentially serious ramifications. A developer on the XDA Developers forum @alephzain uncovered the vulnerability, which could give a malicious app the ability to wipe data, brick a device or access a user's data without their knowledge.
Devices that are vulnerable to attack appear include any device that runs the Exynos 4-based designs, coupled with Samsung's kernel sources. This means that devices including the Meizu MX are also vulnerable to the same exploit along with other Samsung devices. Although no known software uses the exploit maliciously, a senior moderator on the XDA Developers forum @Chainfire has written an APK exploiting the loophole gaining root priveleges "on any Exynos 4-based device."
Another programmer @Supercurio has released a quick fix through Project Voodoo that closes the hack, however, it will depend on Samsung to ensure that the gaping security hole is properly. XDA Developers have contacted Samsung about the matter and report that the company is aware of the issue. However, Samsung had yet to publicly acknowledge the issue at the time of writing. [via TNW]
