MEDIUM 6.5EPSS 2.51%

Does this matter?

Lower severity and a low EPSS score (2.51%). Track it; it rarely justifies an emergency change on its own.

Description

A null pointer dereference flaw was found in the way samba checked database outputs from the LDB database layer. An authenticated attacker could use this flaw to crash a samba server in an Active Directory Domain Controller configuration. Samba versions before 4.7.9 and 4.8.4 are vulnerable.
