Security Bulletin
This security bulletin contains one medium risk vulnerability.
1) Input validation error
EUVDB-ID: #VU74579
Risk: Medium
CVSSv4.0: 6.6 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green]
CVE-ID: CVE-2023-1668
CWE-ID:
CWE-20 - Improper input validation
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to insufficient validation of user-supplied input when processing IP packets. A remote attacker can send specially crafted IP packets with "ip proto" set to "0" and perform a denial of service (DoS) attack.
Successful exploitation of the vulnerability requires that flow rules contain 'set' actions on other fields in the IP protocol header.
