Synopsis

The remote SUSE host is missing one or more security updates.

Description

The remote SUSE Linux SLES12 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2023:0122-1 advisory.

- A null pointer dereference flaw was found in samba's Winbind service in versions before 4.11.15, before 4.12.9 and before 4.13.1. A local user could use this flaw to crash the winbind service causing denial of service. (CVE-2020-14323)

- A flaw was found in samba. A race condition in the password lockout code may lead to the risk of brute force attacks being successful if special conditions are met. (CVE-2021-20251)

- A flaw was found in Samba. Some SMB1 write requests were not correctly range-checked to ensure the client had sent enough data to fulfill the write, allowing server memory contents to be written into the file (or printer) instead of client-supplied data. The client cannot control the area of the server memory written to the file (or printer). (CVE-2022-32742)

- Windows Kerberos RC4-HMAC Elevation of Privilege Vulnerability (CVE-2022-37966)

- Netlogon RPC Elevation of Privilege Vulnerability (CVE-2022-38023)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
