Article contents: Vulnerability Description
CVE-2017-1000379
The Linux Kernel running on AMD64 systems will sometimes map the contents of PIE executable, the heap, or ld.so to where the stack is mapped allowing attackers to more easily manipulate the stack
https://nvd.nist.gov/vuln/detail/CVE-2017-1000379
 
CVE-2017-1000364
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).

NOTE: The initial Linux kernel patch for CVE-2017-1000364, included in TIE Server 2.1.0 Hotfix 1, introduced a regression affecting rust and Java environments. The Linux kernel in TIE Server 2.1.1 Hotfix 3 contains additional patches that solve this issue and simplify the stack allocation validations that mitigate CVE-2017-1000364. See SB10207 for information about other vulnerabilities that TIE Server 2.1.0 Hotfix 1 addresses.
 
CWE-119
The software performs operations on a memory buffer, but it can read from or write to a memory location that is outside of the intended boundary of the buffer.

What is CVSS?
CVSS, or Common Vulnerability Scoring System, is the result of the National Infrastructure Advisory Council’s effort to standardize a system of assessing the criticality of a vulnerability. This system offers an unbiased criticality score between 0 and 10 that customers can use to judge how critical a vulnerability is and plan accordingly. For more information, visit the CVSS website at: http://www.first.org/cvss/.
 
When calculating CVSS scores, McAfee has adopted a philosophy that fosters consistency and repeatability. Our guiding principle for CVSS scoring is to score the exploit under consideration by itself. We consider only the immediate and direct impact of the exploit under consideration. We do not factor into a score any potential follow-on exploits that might be made possible by the successful exploitation of the issue being scored.
