CVE-2022-32744 |
A flaw was found in Samba. The KDC accepts kpasswd requests encrypted with any key known to it. By encrypting forged kpasswd requests with its own key, a user can change other users' passwords, enabling full domain takeover. Published: August 25, 2022; 2:15:10 PM -0400 |
V4.0:(not available) V3.1: 8.8 HIGH V2.0:(not available) |
CVE-2022-32742 |
A flaw was found in Samba. Some SMB1 write requests were not correctly range-checked to ensure the client had sent enough data to fulfill the write, allowing server memory contents to be written into the file (or printer) instead of client-supplied data. The client cannot control the area of the server memory written to the file (or printer). Published: August 25, 2022; 2:15:10 PM -0400 |

CVE-2022-2031 |
A flaw was found in Samba. The security vulnerability occurs when KDC and the kpasswd service share a single account and set of keys, allowing them to decrypt each other's tickets. A user who has been requested to change their password, can exploit this flaw to obtain and use tickets to other services. Published: August 25, 2022; 2:15:09 PM -0400 |

CVE-2021-3670 |
MaxQueryDuration not honoured in Samba AD DC LDAP Published: August 23, 2022; 12:15:09 PM -0400 |
V4.0:(not available) V3.1: 6.5 MEDIUM V2.0:(not available) |
CVE-2021-20316 |
A flaw was found in the way Samba handled file/directory metadata. This flaw allows an authenticated attacker with permissions to read or modify share metadata, to perform this operation outside of the share. Published: August 23, 2022; 12:15:09 PM -0400 |
V4.0:(not available) V3.1: 6.8 MEDIUM V2.0:(not available) |
CVE-2020-25721 |
Kerberos acceptors need easy access to stable AD identifiers (eg objectSid). Samba as an AD DC now provides a way for Linux applications to obtain a reliable SID (and samAccountName) in issued tickets. Published: March 16, 2022; 11:15:09 AM -0400 |

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.

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. Published: March 02, 2022; 6:15:08 PM -0500 |
V4.0:(not available) V3.1: 7.5 HIGH V2.0: 5.0 MEDIUM |
CVE-2021-44141 |
All versions of Samba prior to 4.15.5 are vulnerable to a malicious client using a server symlink to determine if a file or directory exists in an area of the server file system not exported under the share definition. SMB1 with unix extensions has to be enabled in order for this attack to succeed. Published: February 21, 2022; 1:15:08 PM -0500 |
V4.0:(not available) V3.1: 4.3 MEDIUM V2.0: 3.5 LOW |
CVE-2021-44142 |
The Samba vfs_fruit module uses extended file attributes (EA, xattr) to provide "...enhanced compatibility with Apple SMB clients and interoperability with a Netatalk 3 AFP fileserver." Samba versions prior to 4.13.17, 4.14.12 and 4.15.5 with vfs_fruit configured allow out-of-bounds heap read and write via specially crafted extended file attributes. A remote attacker with write access to extended file attributes can execute arbitrary code with the privileges of smbd, typically root. Published: February 21, 2022; 10:15:07 AM -0500 |

CVE-2020-25722 |
Multiple flaws were found in the way samba AD DC implemented access and conformance checking of stored data. An attacker could use this flaw to cause total domain compromise. Published: February 18, 2022; 1:15:08 PM -0500 |
V4.0:(not available) V3.1: 8.8 HIGH V2.0: 6.5 MEDIUM |
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. Published: February 18, 2022; 1:15:08 PM -0500 |
V4.0:(not available) V3.1: 7.2 HIGH V2.0: 9.0 HIGH |
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. Published: February 18, 2022; 1:15:08 PM -0500 |
V4.0:(not available) V3.1: 8.8 HIGH V2.0: 6.5 MEDIUM |
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. Published: February 18, 2022; 1:15:08 PM -0500 |
V4.0:(not available) V3.1: 8.1 HIGH V2.0: 8.5 HIGH |
CVE-2016-2124 |
A flaw was found in the way samba implemented SMB1 authentication. An attacker could use this flaw to retrieve the plaintext password sent over the wire even if Kerberos authentication was required. Published: February 18, 2022; 1:15:08 PM -0500 |
V4.0:(not available) V3.1: 5.9 MEDIUM V2.0: 4.3 MEDIUM |
CVE-2021-43566 |
All versions of Samba prior to 4.13.16 are vulnerable to a malicious client using an SMB1 or NFS race to allow a directory to be created in an area of the server file system not exported under the share definition. Note that SMB1 has to be enabled, or the share also available via NFS in order for this attack to succeed. Published: January 11, 2022; 11:15:07 AM -0500 |
V4.0:(not available) V3.1: 2.5 LOW V2.0: 1.2 LOW |
CVE-2011-2411 |
Unspecified vulnerability on HP NonStop Servers with software H06.x through H06.23.00 and J06.x through J06.12.00, when Samba is used, allows remote authenticated users to execute arbitrary code via unknown vectors. Published: October 02, 2011; 4:55:00 PM -0400 |
