CVSS v3.1 |
| Integer overflow in the Samba daemon (smbd) in Samba 2.x and 3.0.x through 3.0.9 allows remote authenticated users to cause a denial of service (application crash) and possibly execute arbitrary code via a Samba request with a large number of security descriptors that triggers a heap-based buffer overflow. |
| Race condition in Samba smbmnt allows local users to mount file systems in arbitrary locations. |
| Samba Web Administration Tool (SWAT) in Samba 2.0.7 installs the cgi.log logging file with world readable permissions, which allows local users to read sensitive information such as user names and passwords. |
| Buffer overflow in the SMB/CIFS packet fragment re-assembly code for SMB daemon (smbd) in Samba before 2.2.8, and Samba-TNG before 0.3.1, allows remote attackers to execute arbitrary code. |
| The smdb daemon (smbd/service.c) in Samba 3.0.1 through 3.0.22 allows remote attackers to cause a denial of service (memory consumption) via a large number of share connection requests. |
| Multiple buffer overflows in Samba before 2.2.8a may allow remote attackers to execute arbitrary code or cause a denial of service, as discovered by the Samba team and a different vulnerability than CVE-2003-0201. |
| Samba Web Administration Tool (SWAT) in Samba 2.0.7 allows local users to overwrite arbitrary files via a symlink attack on the cgi.log file. |
| Samba Web Administration Tool (SWAT) in Samba 2.0.7 supplies a different error message when a valid username is provided versus an invalid name, which allows remote attackers to identify valid users on the server. |
| Buffer overflow in Samba 2.2.x to 2.2.9, and 3.0.0 to 3.0.4, when the "mangling method = hash" option is enabled in smb.conf, has unknown impact and attack vectors. |
| Buffer overflow in the Samba Web Administration Tool (SWAT) in Samba 3.0.2 to 3.0.4 allows remote attackers to execute arbitrary code via an invalid base-64 character during HTTP basic authentication. |
| smbd in Samba before 2.2.11 allows remote attackers to cause a denial of service (daemon crash) by sending a FindNextPrintChangeNotify request without a previous FindFirstPrintChangeNotify, as demonstrated by the SMB client in Windows XP SP2. |
| distcc 2.x, as used in XCode 1.5 and others, when not configured to restrict access to the server port, allows remote attackers to execute arbitrary commands via compilation jobs, which are executed by the server without authorization checks. |
| Denial of service in Samba NETBIOS name service daemon (nmbd). |
| Samba 3.0.6 and earlier allows remote attackers to cause a denial of service (infinite loop and memory exhaustion) via certain malformed requests that cause new processes to be spawned and enter an infinite loop. |
| smbmnt in Samba 2.x and 3.x on Linux 2.6, when installed setuid, allows local users to gain root privileges by mounting a Samba share that contains a setuid root program, whose setuid attributes are not cleared when the share is mounted. |
| A flaw was found in Samba. The smbd service daemon does not pick up group membership changes when re-authenticating an expired SMB session. This issue can expose file shares until clients disconnect and then connect again. |
| 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. See Microsoft Technical Security Notifications. |
| A path traversal vulnerability was identified in Samba when processing client pipe names connecting to Unix domain sockets within a private directory. Samba typically uses this mechanism to connect SMB clients to remote procedure call (RPC) services like SAMR LSA or SPOOLSS, which Samba initiates on demand. However, due to inadequate sanitization of incoming client pipe names, allowing a client to send a pipe name containing Unix directory traversal characters (../). This could result in SMB clients connecting as root to Unix domain sockets outside the private directory. If an attacker or client managed to send a pipe name resolving to an external service using an existing Unix domain socket, it could potentially lead to unauthorized access to the service and consequential adverse events, including compromise or service crashes. |
| A flaw was found in Samba. It is susceptible to a vulnerability where multiple incompatible RPC listeners can be initiated, causing disruptions in the AD DC service. When Samba's RPC server experiences a high load or unresponsiveness, servers intended for non-AD DC purposes (for example, NT4-emulation "classic DCs") can erroneously start and compete for the same unix domain sockets. This issue leads to partial query responses from the AD DC, causing issues such as "The procedure number is out of range" when using tools like Active Directory Users. This flaw allows an attacker to disrupt AD DC services. |
| A vulnerability was found in Samba's "rpcecho" development server, a non-Windows RPC server used to test Samba's DCE/RPC stack elements. This vulnerability stems from an RPC function that can be blocked indefinitely. The issue arises because the "rpcecho" service operates with only one worker in the main RPC task, allowing calls to the "rpcecho" server to be blocked for a specified time, causing service disruptions. This disruption is triggered by a "sleep()" call in the "dcesrv_echo_TestSleep()" function under specific conditions. Authenticated users or attackers can exploit this vulnerability to make calls to the "rpcecho" server, requesting it to block for a specified duration, effectively disrupting most services and leading to a complete denial of service on the AD DC. The DoS affects all other services as "rpcecho" runs in the main RPC task. |
