It was found that cifs-utils' mount.cifs was invoking a shell when requesting the Samba password, which could be used to inject arbitrary commands. An attacker able to invoke mount.cifs with special permission, such as via sudo rules, could use this flaw to escalate their privileges. Se detectó que mount.cifs de cifs-utils estaba invocando un shell al requerir la contraseña de Samba, que podría ser usado para inyectar comandos arbitrarios. Un atacante capaz de invocar mount.cifs con un permiso especial, como por medio de reglas sudo, podría usar este fallo para escalar sus privilegios. • http://lists.opensuse.org/opensuse-security-announce/2020-09/msg00109.html https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2020-14342 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/DUMRICFXJVCBBOSKZSKT3HFVQM6VPJU3 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/JBNFSTJOQWVPFZAUJNNMAPY45PW5RTTE https://lists.samba.org/archive/samba-technical/2020-September/135747.html https://security.gentoo.org/glsa/202009-16 • CWE-77: Improper Neutralization of Special Elements used in a Command ('Command Injection') CWE-78: Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') •

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.

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.
