1) Infinite loop

EUVDB-ID: #VU15176

Risk: Low

CVSSv3.1: 4.6 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L/E:U/RL:O/RC:C]

CVE-ID: CVE-2018-11797

CWE-ID: CWE-835 - Loop with Unreachable Exit Condition ('Infinite Loop')

Exploit availability: No

Description

The vulnerability vulnerability allows an unauthenticated, remote attacker to cause a denial of service (DoS) condition on a target system.
