Dirty COW: The Linux Developer kernel, Greg Kroah-Hartman announced three new maintenance updates for Linux 4.8, 4.7 and 4.4 of the LTS kernel series, which fix an important vulnerability security.
The Linux kernel vulnerability is known as "Dirty COW," and is documented in CVE-2016-5195. In fact, it is a very bad bug that could be used by local users to write to any file even if it had read only rights.
The worst thing is that this security flaw exists from the Linux kernel at least from the 2.6.x series that reached the end of its life in February of this year.
“This is an ancient one error which I tried to determine once eleven years ago,” Linus reveals Torvalds in an email.
Of course, those who use Linux should upgrade their Kernel directly.
