    samba vulnerabilities

    A security issue affects these releases of Ubuntu and its derivatives:

    • Ubuntu 17.10
    • Ubuntu 16.04 LTS
    • Ubuntu 14.04 LTS

    Several security issues were fixed in Samba.

    Software Description

    • samba - SMB/CIFS file, print, and login server for Unix

    Björn Baumbach discovered that Samba incorrectly validated permissions when changing account passwords via LDAP. An authenticated attacker could use this issue to change the password of other users, including administrators, and perform actions as those users. (CVE-2018-1057)

    It was discovered that Samba incorrectly validated inputs to the RPC spoolss service. An authenticated attacker could use this issue to cause the service to crash, resulting in a denial of service. (CVE-2018-1050)
