A new bug in the Linux kernel was discovered by a researcher named Philip Pettersson, who managed to create an exploit to gain root access in the Linux Shell by exploiting a flaw in the program's code.
Second the information, this bug has existed in the Linux Kernel for 5 years without being explored so far, it affects virtually all Linux distros, including Ubuntu and Red Hat. This Linux kernel vulnerability ( CVE-2016-8655 ) dating back to 2011 was disclosed this week, it may allow an unprivileged local user to access as root by exploiting a condition of af_packet in the Linux kernel. Philip Pettersson, the researcher who discovered the flaw, was able to create an exploit for root access on an Ubuntu 16.04 LTS (Kernel 4.4), you can read the bug log in detail. on this page.
Kernel 4.9, which was recently released, is already coming out with this bug fix, for other distros that use different versions, like Ubuntu itself with Kernel 4.4 LTS, it is worth keeping the system up to date as Canonical has fixed the issue through Security patches too.
Regardless of the distribution you use, it's always worth keeping the system up to date, so you avoid problems.
NOTE: Curious that always with the news of the bug comes the news of his correction, right?
See you next time!
