Alpine: samba: security update to 4.15.9-r0

high Tenable Cloud Security Plugin ID 407084

Description

There are packages installed that are affected by multiple vulnerabilities referenced in the following CVEs:

- A flaw was found in Samba. Samba AD users can cause the server to access uninitialized data with an LDAP
add or modify the request, usually resulting in a segmentation fault. (CVE-2022-32745)

- MaxQueryDuration not honoured in Samba AD DC LDAP (CVE-2021-3670)

- A flaw was found in Samba. The security vulnerability occurs when KDC and the kpasswd service share a
single account and set of keys, allowing them to decrypt each other's tickets. A user who has been
requested to change their password, can exploit this flaw to obtain and use tickets to other services.
(CVE-2022-2031)

- 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)

- A flaw was found in Samba. The KDC accepts kpasswd requests encrypted with any key known to it. By
encrypting forged kpasswd requests with its own key, a user can change other users' passwords, enabling
full domain takeover. (CVE-2022-32744)
