There is no fixed version for samba.
Overview
Affected versions of this package are vulnerable to Incorrect Permission Assignment for Critical Resource through the mkhomedir process in pam_winbind when it is enabled in the configuration. An attacker can cause ownership of critical system directories such as / to be changed by initiating a PAM session for an account whose home directory resolves to /, potentially resulting in denial of service affecting SSH, sudo, and package management. This is only exploitable if mkhomedir is explicitly enabled in pam_winbind.conf and a PAM session is opened for an account with a home directory set to / or another sensitive system path.
Workaround
This vulnerability can be mitigated by not enabling mkhomedir in pam_winbind.conf on systems where any account may resolve to a home directory of / or another sensitive system path.
