Scientific Linux Security Update : kernel on SL7.x x86_64 (Stack Clash)

Medium Nessus Plugin ID 100906


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


Security Fix(es) :

- A flaw was found in the way memory was being allocated on the stack for user space binaries. If heap (or different memory region) and stack memory regions were adjacent to each other, an attacker could use this flaw to jump over the stack guard gap, cause controlled memory corruption on process stack or the adjacent memory region, and thus increase their privileges on the system. This is a kernel-side mitigation which increases the stack guard gap size from one page to 1 MiB to make successful exploitation of this issue more difficult.
(CVE-2017-1000364, Important)
