Technical Details & Description:
================================
A local buffer overflow vulnerability has been discovered in the official Intel System CU 14.0 and 14.1 utilities.
The vulnerability can be exploited by local attackers to overwrite active registers to compromise the process or
affected computer system.
Intel system configuration utilities are vulnerable to a denial of service, caused by a classic buffer overflow.
By sending a specially-crafted request, a local authenticated attacker could exploit this vulnerability to cause
a denial of service condition.
Affected are versions of syscfg.exe before release 14.0 build 16 or for systems based on Intelยฎ C620 Series
Chipsets 14.1 build 19. Affected are Versions of selview.exe before release 14.0 build 21 or for systems based
on Intelยฎ C620 Series Chipsets before 14.0 build 11.
Exploitation of the local buffer overflow vulnerability requires no user interaction and system process privileges.
Successful exploitation of the buffer overflow vulnerability results in a compromise of the local system process or
affected computer system.
Vulnerable File(s):
[+] syscfg.exe
[+] selview.exe
