Security Bulletin

This security bulletin contains information about 7 vulnerabilities.

1) Resource exhaustion

EUVDB-ID: #VU80481

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-2023-32247

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 ksmbd does not properly control consumption of internal resources when handling SMB2_SESSION_SETUP commands. A remote attacker can send specially crafted data to the server during session setup, trigger memory exhaustion and perform a denial of service (DoS) attack.

Mitigation

Install updates from vendor's repository.
