CVE-2013-4496 [MEDIUM] CVE-2013-4496 samba: Password lockout not enforced for SAMR password changes
CVE-2013-4496 samba: Password lockout not enforced for SAMR password changes
From upstream samba advisory:
Samba versions 3.4.0 and above allow the administrator to implement locking out Samba accounts after a number of bad password attempts.
However, all released versions of Samba did not implement this check for password changes, such as are available over multiple SAMR and RAP interfaces, allowing password guessing attacks.
Most sites do not configure the bad password lockout feature. Typically it is only enabled when Samba is configured as a Domain Controller, so most file server deployments are not impacted.
This flaw only affects samba when deployed as a Primary Domain Controller.
