Dirty COW: Ο προγραμματιστής του Linux kernel, Greg Kroah-Hartman ανακοίνωσε τρεις νέες ενημερώσεις συντήρησης για τα Linux 4.8, 4.7 και 4.4 της σειράς πυρήνα LTS, που διορθώνουν μια σημαντική vulnerability security.
The Linux kernel vulnerability is known as "Dirty COW," and is documented in CVE-2016-5195. In fact, it is a very ugly bug that could be used by locals users to write to any file even if it had read only permissions.
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 bug that I tried to fix once eleven years ago," Linus reveals Torvalds in an email.
Of course, those who use Linux should upgrade their Kernel directly.
