Security Bulletin

This security bulletin contains information about 6 vulnerabilities.

1) Input validation error

EUVDB-ID: #VU85682

Risk: Low

CVSSv4.0: 4.3 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear]

CVE-ID: CVE-2023-46838

CWE-ID: CWE-20 - Improper input validation

Exploit availability: No

Description

The vulnerability allows an unprivileged guest to perform a denial of service (DoS) attack.

The vulnerability exists due to insufficient validation of network packets at the backend. An unprivileged guest can send zero-length packets to the OS kernel and perform a denial of service (DoS) attack.

Mitigation

Install updates from vendor's repository.

Q & A

Can this vulnerability be exploited remotely?

No. This vulnerability can be exploited locally. The attacker should have authentication credentials and successfully authenticate on the system.

2) Resource exhaustion

EUVDB-ID: #VU88378

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-2023-52340

CWE-ID: CWE-400 - Resource exhaustion

Exploit availability: No

Description

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to an error when processing very large ICMPv6 packets. A remote attacker can send a flood of IPv6 ICMP6 PTB messages, cause the high lock contention and increased CPU usage, leading to a denial of service.

Successful vulnerability exploitation requires a attacker to be on the local network or have a high bandwidth connection.

Mitigation

Install updates from vendor's repository.
