All versions of Samba from 4.0.0 onwards are vulnerable to a denial of service attack when the RPC spoolss service is configured to be run as an external daemon.

MEDIUM 4.3EPSS 6.51%

Does this matter?

Lower severity and a low EPSS score (6.51%). Track it; it rarely justifies an emergency change on its own.

Description

All versions of Samba from 4.0.0 onwards are vulnerable to a denial of service attack when the RPC spoolss service is configured to be run as an external daemon. Missing input sanitization checks on some of the input parameters to spoolss RPC calls could cause the print spooler service to crash.
