Security Bulletin

This security bulletin contains information about 2 vulnerabilities.

1) Out-of-bounds read

EUVDB-ID: #VU70471

Risk: Medium

CVSSv4.0: 1.7 [CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:L/VI:N/VA:L/SC:N/SI:N/SA:N/E:U/U:Green]

CVE-ID: CVE-2022-4337

CWE-ID: CWE-125 - Out-of-bounds read

Exploit availability: No

Description

The 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.

Mitigation

Update the affected package openvswitch to the latest version.

2) Integer underflow

EUVDB-ID: #VU70459

Risk: High

CVSSv4.0: 7.2 [CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Amber]

CVE-ID: CVE-2022-4338

CWE-ID: CWE-191 - Integer underflow

Exploit availability: No

Description

The 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.

Mitigation

Update the affected package openvswitch to the latest version.
