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

high Tenable Cloud Security Plugin ID 462444

Description

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

 - An infinite loop vulnerability was found in Samba's mdssvc RPC service for Spotlight. When parsing
 Spotlight mdssvc RPC packets sent by the client, the core unmarshalling function sl_unpack_loop() did not
 validate a field in the network packet that contains the count of elements in an array-like structure. By
 passing 0 as the count value, the attacked function will run in an endless loop consuming 100% CPU. This
 flaw allows an attacker to issue a malformed RPC request, triggering an infinite loop, resulting in a
 denial of service condition. (CVE-2023-34966)

Solution

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