VCID-8716-eb6d-aaac Aliases: CVE-2020-14383	A flaw was found in samba's DNS server. An authenticated user could use this flaw to the RPC server to crash. This RPC server, which also serves protocols other than dnsserver, will be restarted after a short delay, but it is easy for an authenticated non administrative attacker to crash it again as soon as it returns. The Samba DNS server itself will continue to operate, but many RPC services will not.	2:4.11.6+dfsg-0ubuntu1.6 Affected by 10 other vulnerabilities.

VCID-dc8e-1wpk-aaak Aliases: CVE-2020-1472	An elevation of privilege vulnerability exists when an attacker establishes a vulnerable Netlogon secure channel connection to a domain controller, using the Netlogon Remote Protocol (MS-NRPC). An attacker who successfully exploited the vulnerability could run a specially crafted application on a device on the network. To exploit the vulnerability, an unauthenticated attacker would be required to use MS-NRPC to connect to a domain controller to obtain domain administrator access. Microsoft is addressing the vulnerability in a phased two-part rollout. These updates address the vulnerability by modifying how Netlogon handles the usage of Netlogon secure channels. For guidelines on how to manage the changes required for this vulnerability and more information on the phased rollout, see How to manage the changes in Netlogon secure channel connections associated with CVE-2020-1472 (updated September 28, 2020). When the second phase of Windows updates become available in Q1 2021, customers will be notified via a revision to this security vulnerability. If you wish to be notified when these updates are released, we recommend that you register for the security notifications mailer to be alerted of content changes to this advisory.

VCID-mgzj-9vj2-aaad Aliases: CVE-2021-20254	A flaw was found in samba. The Samba smbd file server must map Windows group identities (SIDs) into unix group ids (gids). The code that performs this had a flaw that could allow it to read data beyond the end of the array in the case where a negative cache entry had been added to the mapping cache. This could cause the calling code to return those values into the process token that stores the group membership for a user.

VCID-ny1w-v2d1-aaaj Aliases: CVE-2021-23192	A flaw was found in the way samba implemented DCE/RPC. If a client to a Samba server sent a very large DCE/RPC request, and chose to fragment it, an attacker could replace later fragments with their own data, bypassing the signature requirements.	2:4.13.14+dfsg-0ubuntu0.20.04.1 Affected by 0 other vulnerabilities.
VCID-pe83-8mqu-aaaf Aliases: CVE-2020-10760	A use-after-free flaw was found in all samba LDAP server versions before 4.10.17, before 4.11.11, before 4.12.4 used in a AC DC configuration.

VCID-qmfb-r5jc-aaaq Aliases: CVE-2021-3738	In DCE/RPC it is possible to share the handles (cookies for resource state) between multiple connections via a mechanism called 'association groups'. These handles can reference connections to our sam.ldb database. However while the database was correctly shared, the user credentials state was only pointed at, and when one connection within that association group ended, the database would be left pointing at an invalid 'struct session_info'. The most likely outcome here is a crash, but it is possible that the use-after-free could instead allow different user state to be pointed at and this might allow more privileged access.	2:4.13.14+dfsg-0ubuntu0.20.04.1 Affected by 0 other vulnerabilities.
VCID-r2ub-pwv4-aaaa Aliases: CVE-2020-25717	A flaw was found in the way Samba maps domain users to local users. An authenticated attacker could use this flaw to cause possible privilege escalation.	2:4.13.14+dfsg-0ubuntu0.20.04.1 Affected by 0 other vulnerabilities.
VCID-sm2p-s4x5-aaae Aliases: CVE-2020-25719	A flaw was found in the way Samba, as an Active Directory Domain Controller, implemented Kerberos name-based authentication. The Samba AD DC, could become confused about the user a ticket represents if it did not strictly require a Kerberos PAC and always use the SIDs found within. The result could include total domain compromise.	2:4.13.14+dfsg-0ubuntu0.20.04.1 Affected by 0 other vulnerabilities.
VCID-svdc-81bn-aaak Aliases: CVE-2020-25718	A flaw was found in the way samba, as an Active Directory Domain Controller, is able to support an RODC (read-only domain controller). This would allow an RODC to print administrator tickets.	2:4.13.14+dfsg-0ubuntu0.20.04.1 Affected by 0 other vulnerabilities.
VCID-sxbn-732u-aaaa Aliases: CVE-2020-10730	A NULL pointer dereference, or possible use-after-free flaw was found in Samba AD LDAP server in versions before 4.10.17, before 4.11.11 and before 4.12.4. Although some versions of Samba shipped with Red Hat Enterprise Linux do not support Samba in AD mode, the affected code is shipped with the libldb package. This flaw allows an authenticated user to possibly trigger a use-after-free or NULL pointer dereference. The highest threat from this vulnerability is to system availability.	2:4.10.7+dfsg-0ubuntu2.6 Affected by 19 other vulnerabilities.

Vulnerability	Summary	Aliases
VCID-7g9g-ydhg-aaae	There is an issue in all samba 4.11.x versions before 4.11.5, all samba 4.10.x versions before 4.10.12 and all samba 4.9.x versions before 4.9.18, where the removal of the right to create or modify a subtree would not automatically be taken away on all domain controllers.	CVE-2019-14902
VCID-t8qc-uqjq-aaah	There is a use-after-free issue in all samba 4.9.x versions before 4.9.18, all samba 4.10.x versions before 4.10.12 and all samba 4.11.x versions before 4.11.5, essentially due to a call to realloc() while other local variables still point at the original buffer.	CVE-2019-19344
VCID-tbht-4b8p-aaap	All samba versions 4.9.x before 4.9.18, 4.10.x before 4.10.12 and 4.11.x before 4.11.5 have an issue where if it is set with "log level = 3" (or above) then the string obtained from the client, after a failed character conversion, is printed. Such strings can be provided during the NTLMSSP authentication exchange. In the Samba AD DC in particular, this may cause a long-lived process(such as the RPC server) to terminate. (In the file server case, the most likely target, smbd, operates as process-per-client and so a crash there is harmless).	CVE-2019-14907
