CVSS v3.1 |
| 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. |
| The process_logon_packet function in the nmbd server for Samba 3.0.6 and earlier, when domain logons are enabled, allows remote attackers to cause a denial of service via a SAM_UAS_CHANGE request with a length value that is larger than the number of structures that are provided. |
| Samba 1.9.18 inadvertently includes a prototype application, wsmbconf, which is installed with incorrect permissions including the setgid bit, which allows local users to read and write files and possibly gain privileges via bugs in the program. |
| Integer underflow in pppd in cbcp.c for ppp 2.4.1 allows remote attackers to cause a denial of service (daemon crash) via a CBCP packet with an invalid length value that causes pppd to access an incorrect memory location. |
| The mksmbpasswd shell script (mksmbpasswd.sh) in Samba 3.0.0 and 3.0.1, when creating an account but marking it as disabled, may overwrite the user password with an uninitialized buffer, which could enable the account with a more easily guessable password. |
| jitterbug 1.6.2 does not properly sanitize inputs, which allows remote authenticated users to execute arbitrary commands. |
| Denial of service in Samba NETBIOS name service daemon (nmbd). |
| Samba before 2.2.5 does not properly terminate the enum_csc_policy data structure, which may allow remote attackers to execute arbitrary code via a buffer overflow attack. |
| 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. |
| 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 allows remote attackers to cause a denial of service by repeatedly submitting a nonstandard URL in the GET HTTP request and forcing it to restart. |
| The ms_fnmatch function in Samba 3.0.4 and 3.0.7 and possibly other versions allows remote authenticated users to cause a denial of service (CPU consumption) via a SAMBA request that contains multiple * (wildcard) characters. |
| rsync, when running in daemon mode, does not properly call setgroups before dropping privileges, which could provide supplemental group privileges to local users, who could then read certain files that would otherwise be disallowed. |
| 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. |
| Multiple memory leaks in Samba before 3.0.6 allow attackers to cause a denial of service (memory consumption). |
| 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. |
| The unix_clean_name function in Samba 2.2.x through 2.2.11, and 3.0.x before 3.0.2a, trims certain directory names down to absolute paths, which could allow remote attackers to bypass the specified share restrictions and read, write, or list arbitrary files via "/.////" style sequences in pathnames. |
| Buffer overflow in samba 2.2.2 through 2.2.6 allows remote attackers to cause a denial of service and possibly execute arbitrary code via an encrypted password that causes the overflow during decryption in which a DOS codepage string is converted to a little-endian UCS2 unicode string. |
| 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. |
