larger stack guard gap, between vmas in kernel-mm CVE-2017-1000364 (aka Stack Clash)
An issue was discovered in the size of the stack guard page on Linux, specifically a 4k stack guard page is not sufficiently large and can be "jumped" over (the stack guard page is bypassed), this affects Linux Kernel versions 4.11.5 and earlier (the stackguard page was introduced in 2010).
Patch upstream has to be backported to 3.4.108 (maybe look at debian-wheezy 3.2.89-1 source)...
CVSS v3 Base Score: 9.8 Critical

larger stack guard gap, between vmas in kernel-mm and glibc CVE-2017-1000364 CVE-2017-1000365 (aka Stack Clash)
An issue was discovered in the size of the stack guard page on Linux, specifically a 4k stack guard page is not sufficiently large and can be "jumped" over (the stack guard page is bypassed), this affects Linux Kernel versions 4.11.5 and earlier (the stackguard page was introduced in 2010).
Patch The Linux Kernel imposes a size restriction on the arguments and environmental strings passed through RLIMIT_STACK/RLIM_INFINITY (1/4 of the size), but does not take the argument and environment pointers into account, which allows attackers to bypass this limitation. This affects Linux Kernel versions 4.11.5 and earlier. It appears that this feature was introduced in the Linux Kernel version 2.6.23.
