Abstract Advisory Information:
==============================
An independent vulnerability laboratory researcher discovered an unquoted
service path privilege escalation vulnerability in the Intel(R) HD Graphics
v10.x software.
Vulnerability Disclosure Timeline:
==================================
2016-11-02: Public Disclosure (Vulnerability Laboratory)
Discovery Status:
=================
Published
Affected Product(s):
====================
Intel Atom
Product: Intel(R) HD Graphics - Software 10.18.10.4358
Exploitation Technique:
=======================
Local
Severity Level:
===============
Medium
Technical Details & Description:
================================
The application suffers from a search path issue unquoted impact on Intel(R) HD
Graphics. This could potentially allow
authorized but unprivileged local user accounts with system access to
unauthorized execute arbitrary code with system
privileges of the affected software process.
The security risk of the software vulnerability is estimated as medium with a
cvss (common vulnerability scoring system) count of 4.4.
Exploitation of the software vulnerability requires a low privilege system user
account with restricted access and without user interaction.
Successful exploitation of the vulnerability results in system process
compromise and further manipulation or exploitation to compromise the
local computer operating system.
Proof of Concept (PoC):
=======================
The issue can be exploited by local attackers with restricted system user
account or network access and without user interaction.
For security demonstration or to reproduce the vulnerability follow the
provided information and steps below to continue.
