Security Bulletin

This security bulletin contains information about 6 vulnerabilities.

1) Stack-based buffer overflow

EUVDB-ID: #VU14162

Risk: Low

CVSSv4.0: 5.4 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:P/U:Clear]

CVE-ID: CVE-2018-14679

CWE-ID: CWE-121 - Stack-based buffer overflow

Exploit availability: No

Description

The vulnerability allows a local attacker to cause DoS condition on the target system.
