Advisory Release Date: 2019-01-25 02:42 Pacific
Severity: Medium

Issue Overview:

A null pointer dereference flaw was found in Samba RPC external printer service. An attacker could use this flaw to cause the printer spooler service to crash. (CVE-2018-1050 )

A heap-buffer overflow was found in the way samba clients processed extra long filename in a directory listing. A malicious samba server could use this flaw to cause arbitrary code execution on a samba client. (CVE-2018-10858 )

A flaw was found in the way samba allowed the use of weak NTLMv1 authentication even when NTLMv1 was explicitly disabled. A man-in-the-middle attacker could use this flaw to read the credential and other details passed between the samba server and client. (CVE-2018-1139 )
