========================================================================== Ubuntu Security Notice USN-3738-1 August 14, 2018
samba vulnerabilities ==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 18.04 LTS - Ubuntu 16.04 LTS - Ubuntu 14.04 LTS
Summary:
Several security issues were fixed in Samba.
Software Description: - samba: SMB/CIFS file, print, and login server for Unix
Details:
Svyatoslav Phirsov discovered that the Samba libsmbclient library incorrectly handled extra long filenames. A malicious server could use this issue to cause Samba to crash, resulting in a denial of service, or possibly execute arbitrary code. (CVE-2018-10858)
Volker Mauel discovered that Samba incorrectly handled database output. When used as an Active Directory Domain Controller, a remote authenticated attacker could use this issue to cause Samba to crash, resulting in a denial of service. This issue only affected Ubuntu 18.04 LTS. (CVE-2018-10918)
Phillip Kuhrt discovered that the Samba LDAP server incorrectly handled certain confidential attribute values. A remote authenticated attacker could possibly use this issue to obtain certain sensitive information. (CVE-2018-10919)
Vivek Das discovered that Samba incorrectly handled NTLMv1 being explicitly disabled on the server. A remote user could possibly be authenticated using NTLMv1, contrary to expectations. This issue only affected Ubuntu 18.04 LTS. (CVE-2018-1139)
Update instructions:
The problem can be corrected by updating your system to the following package versions:
Ubuntu 18.04 LTS: libsmbclient 2:4.7.6+dfsg~ubuntu-0ubuntu2.2 samba 2:4.7.6+dfsg~ubuntu-0ubuntu2.2
Ubuntu 16.04 LTS: libsmbclient 2:4.3.11+dfsg-0ubuntu0.16.04.15 samba 2:4.3.11+dfsg-0ubuntu0.16.04.15
Ubuntu 14.04 LTS: libsmbclient 2:4.3.11+dfsg-0ubuntu0.14.04.16 samba 2:4.3.11+dfsg-0ubuntu0.14.04.16
In general, a standard system update will make all the necessary changes.
