The Dirty Cow is the latest flaw discovered in Linux. This security problem was revealed at the end of last month, but has been in this operating system there are many year.
But, as alertámos, the Dirty Cow is also on Android, where it can be exploited. Google already should have fixed, but apparently only release the fix in December.
This failure has a high degree of severity in Linux for various reasons. The most important is because it is for more than 9 years in the Linux kernel, without that has been discovered and corrected. This age leads to the fact that many systems can not be updated, and that, therefore, become permanently exposed.
To be exploited, and already the is being on Linux systems, gives users access to accounts with more permissions, among them the root, which allows you to control after the system.
But the Android is exposed to the Dirty Cow and Google decided not to include the fix for this fault in the last monthly update safety. The more likely it is that Google needs more a month so that you can correct the failure and that the bid for the partners to send the updates to the devices.
The Dirty Cow is being used to improve Android
But not everything are bad news with regards to the Dirty Cow and to Android. This flaw is being actively exploited to something that many want. It was with the Dirty Cow that was able to do root the new smartphone from Google, sold at Verizon.
Many thought that Google were this problem is already this month and advised users to delay the update if you want the bootloaders of Android remain unblocked.
do Not understand the reason for Google taking so long to resolve this serious problem of security, since most of the Linux distributions already have the Dirty Cow resolved.
