Scientific Linux Security Update : kernel on SL7.x x86_64 (Dirty COW)

High Nessus Plugin ID 94248

Synopsis

The remote Scientific Linux host is missing one or more security updates.

Description

Security Fix(es) :

- A race condition was found in the way the Linux kernel's memory subsystem handled the copy-on-write (COW) breakage of private read-only memory mappings. An unprivileged, local user could use this flaw to gain write access to otherwise read-only memory mappings and thus increase their privileges on the system.
(CVE-2016-5195, Important)

Solution
