Security Bulletin
This security bulletin contains information about 3 vulnerabilities.
EUVDB-ID: #VU70471
Risk: Medium
CVSSv3.1: 4.2 [CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:L/I:N/A:L/E:U/RL:O/RC:C]
CVE-ID: CVE-2022-4337
CWE-ID:
CWE-125 - Out-of-bounds read
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to gain access to potentially sensitive information or perform a denial of service (DoS) attack.
The vulnerability exists due to a boundary condition when parsing Auto Attach TLV. A remote attacker can send specially crafted LLDP messages to the affected system, trigger an out-of-bounds read error and read contents of memory on the system of perform a denial of service (DoS) attack.
Update the affected package openvswitch to the latest version.

EUVDB-ID: #VU70459
Risk: High
CVSSv3.1: 7.1 [CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H/E:U/RL:O/RC:C]
CVE-ID: CVE-2022-4338
CWE-ID:
CWE-191 - Integer underflow
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to integer underflow when parsing Auto Attach TLV. A remote attacker can send specially crafted LLDP messages to the affected system, trigger an integer underflow and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
Note, by default interfaces are not configured to process LLDP messages.
Update the affected package openvswitch to the latest version.

EUVDB-ID: #VU74579
Risk: Medium
CVSSv3.1: 6.5 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H/E:U/RL:O/RC:C]
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.
Update the affected package openvswitch to the latest version.
