Summary

samba vulnerability

Details

Tom Tervoort discovered that the Netlogon protocol implemented by Samba incorrectly handled the authentication scheme. A remote attacker could use this issue to forge an authentication token and steal the credentials of the domain admin.

This update fixes the issue by changing the "server schannel" setting to default to "yes", instead of "auto", which will force a secure netlogon channel. This may result in compatibility issues with older devices. A future update may allow a finer-grained control over this setting.
