Input validation error in Open vSwitch - CVE-2023-1668

Vulnerability identifier: #VU74579

CSH Severity: Medium

CVSS v4: 8.7 [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]

CVE-ID: CVE-2023-1668

CWE-ID: CWE-20

Exploitation vector: Remote access

Exploit availability: No public exploit available

The 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.
