Security Bulletin
This security bulletin contains information about 4 vulnerabilities.
1) Stack-based buffer overflow
EUVDB-ID: #VU15158
Risk: High
CVSSv3.1: 8.8 [CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:H/I:H/A:H/E:U/RL:U/RC:C]
CVE-ID: CVE-2018-14818
CWE-ID:
CWE-121 - Stack-based buffer overflow
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to stack-based buffer overflow when handling malicious input. A remote unauthenticated attacker can trick the victim into visiting a specially crafted website, trigger memory corruption and execute arbitrary code with elevated privileges.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
MitigationCybersecurity Help is currently unaware of any solutions addressing the vulnerability.
