high Tenable Self-Hosted Container Security Plugin ID 407116

Description

There are packages installed that are affected by multiple vulnerabilities referenced in the following CVEs:

- A flaw was found in the way samba before 4.7.9 and 4.8.4 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)

- 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.
Samba versions before 4.6.16, 4.7.9 and 4.8.4 are vulnerable. (CVE-2018-10858)

- 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. (CVE-2018-10918)

- The Samba Active Directory LDAP server was vulnerable to an information disclosure flaw because of missing
access control checks. An authenticated attacker could use this flaw to extract confidential attribute
values using LDAP search expressions. Samba versions before 4.6.16, 4.7.9 and 4.8.4 are vulnerable.
