Security Bulletin

This security bulletin contains information about 3 vulnerabilities.

1) Buffer overflow

EUVDB-ID: #VU42519

Risk: Low

CVSSv4.0: 1.2 [CVSS:4.0/AV:N/AC:L/AT:N/PR:H/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:U/U:Clear]

CVE-ID: CVE-2013-4239

CWE-ID: CWE-119 - Memory corruption

Exploit availability: No

Description

The vulnerability allows a remote #AU# to perform service disruption.
