Samba is the standard windows interoperability suite of programs for linux and unix.
Security fix(es): a flaw was found in the samba client, all samba versions before samba 4.11.2, 4.10.10 and 4.9.15, where a malicious server can supply a pathname to the client with separators.
This could allow the client to access files and folders outside of the smb network pathnames.
An attacker could use this vulnerability to create files outside of the current working directory using the privileges of the client user.(cve-2019-10218) a flaw was found in samba, all versions starting samba 4.5.0 before samba 4.9.15, samba 4.10.10, samba 4.11.2, in the way it handles a user password change or a new password for a samba user.
The samba active directory domain controller can be configured to use a custom script to check for password complexity.
This configuration can fail to verify password complexity when non-ascii characters are used in the password, which could lead to weak passwords being set for samba users, making it vulnerable to dictionary attacks.(cve-2019-14833) a flaw was found in samba 4.0.0 before samba 4.9.15 and samba 4.10.x before 4.10.10.
An attacker can crash ad dc ldap server via dirsync resulting in denial of service.
Privilege escalation is not possible with this issue.(cve-2019-14847)
