Description

CVE-2017-1000364
A flaw was found in how memory is allocated on the stack for user space binaries. If heap (or other memory region) and stack memory regions are adjacent to each other, an attacker can use this flaw to jump over the stack guard gap, cause controlled memory corruption on the process stack or the adjacent memory region, and increase their privileges on the system.
https://nvd.nist.gov/vuln/detail/CVE-2017-1000364
 
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.

CVE-2017-3907
Code injection vulnerability in the ePolicy Orchestrator (ePO) extension in McAfee Threat Intelligence Exchange Server 2.1.0 and earlier allows remote attackers to execute arbitrary HTML code to be reflected in the response web page via unspecified attack vector.
https://nvd.nist.gov/vuln/detail/CVE-2017-3907 

CWE-80
The software receives input from an upstream component, but it does not neutralize or incorrectly neutralizes special characters such as "<", ">", and "&" that could be interpreted as web-scripting elements when they are sent to a downstream component that processes web pages.

Remediation

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. McAfee recommends installing TIE Server 2.1.1 Hotfix 3 to address this issue. See SB10229 for updated information.

This issue is resolved in TIE Server 2.1.0 Hotfix 1.

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 successful exploitation of the issue being scored
