Echo: samba: security update to 2:4.17.10+dfsg-0+deb12u1

medium Tenable Cloud Security Plugin ID 461193

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - An out-of-bounds read vulnerability was found in Samba due to insufficient length checks in
 winbindd_pam_auth_crap.c. When performing NTLM authentication, the client replies to cryptographic
 challenges back to the server. These replies have variable lengths, and Winbind fails to check the lan
 manager response length. When Winbind is used for NTLM authentication, a maliciously crafted request can
 trigger an out-of-bounds read in Winbind, possibly resulting in a crash. (CVE-2022-2127)

Solution

Update the samba library and its related packages to version 2:4.17.10+dfsg-0+deb12u1 or later.
