ID CVE-2018-16851
Summary Samba from version 4.0.0 and before versions 4.7.12, 4.8.7, 4.9.3 is vulnerable to a denial of service. During the processing of an LDAP search before Samba's AD DC returns the LDAP entries to the client, the entries are cached in a single memory object with a maximum size of 256MB. When this size is reached, the Samba process providing the LDAP service will follow the NULL pointer, terminating the process. There is no further vulnerability associated with this issue, merely a denial of service.

    description Several vulnerabilities have been discovered in Samba, a SMB/CIFS file, print, and login server for Unix. The Common Vulnerabilities and Exposures project identifies the following issues : CVE-2018-14629 Florian Stuelpner discovered that Samba is vulnerable to infinite query recursion caused by CNAME loops, resulting in denial of service. CVE-2018-16851 Garming Sam of the Samba Team and Catalyst discovered a NULL pointer dereference vulnerability in the Samba AD DC LDAP server allowing a user able to read more than 256MB of LDAP entries to crash the Samba AD DC's LDAP server. For Debian 8 'Jessie', these problems have been fixed in version 2:4.2.14+dfsg-0+deb8u11. We recommend that you upgrade your samba packages. NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

    description The samba project reports : All versions of Samba from 4.0.0 onwards are vulnerable to infinite query recursion caused by CNAME loops. Any dns record can be added via ldap by an unprivileged user using the ldbadd tool, so this is a security issue. When configured to accept smart-card authentication, Samba's KDC will call talloc_free() twice on the same memory if the principal in a validly signed certificate does not match the principal in the AS-REQ. During the processing of an LDAP search before Samba's AD DC returns the LDAP entries to the client, the entries are cached in a single memory object with a maximum size of 256MB. When this size is reached, the Samba process providing the LDAP service will follow the NULL pointer, terminating the process. During the processing of an DNS zone in the DNS management DCE/RPC server, the internal DNS server or the Samba DLZ plugin for BIND9, if the DSPROPERTY_ZONE_MASTER_SERVERS property or DSPROPERTY_ZONE_SCAVENGING_SERVERS property is set, the server will follow a NULL pointer and terminate A user in a Samba AD domain can crash the KDC when Samba is built in the non-default MIT Kerberos configuration. AD DC Configurations watching for bad passwords (to restrict brute forcing of passwords) in a window of more than 3 minutes may not watch for bad passwords at all.

    description The version of Samba running on the remote host is 4.7.x prior to 4.7.12, or 4.8.x prior to 4.8.7, or 4.9.x prior to 4.9.3. It is, therefore, affected by multiple vulnerabilities. Notes: - Refer to vendor advisories for possible workarounds. - CVE-2018-16852 and CVE-2018-16857 only apply to 4.9.x. Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.
