Samba is an open-source implementation of the Server Message Block (SMB) protocol and the related Common Internet File System (CIFS) protocol, which allow PC-compatible machines to share files, printers, and various information.

Security Fix(es):

* samba: smbd allows client access to unix domain sockets on the file system as root (CVE-2023-3961) * samba: SMB clients can truncate files with read-only permissions (CVE-2023-4091) * samba: "rpcecho" development server allows denial of service via sleep() call on AD DC (CVE-2023-42669)

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.

Samba is a suite of programs for Linux and Unix to interoperate with Windows. Security Fix(es): A vulnerability was discovered in Samba, where the flaw allows SMB clients to truncate files, even with read-only permissions when the Samba VFS module &quot;acl_xattr&quot; is configured with &quot;acl_xattr:ignore system acls = yes&quot;. The SMB protocol allows opening files when the client requests read-only access but then implicitly truncates the opened file to 0 bytes if the client specifies a separate OVERWRITE create disposition request. The issue arises in configurations that bypass kernel file system permissions checks, relying solely on Samba&apos;s permissions.(CVE-2023-4091) A vulnerability was found in Samba&apos;s &quot;rpcecho&quot; development server, a non-Windows RPC server used to test Samba&apos;s DCE/RPC stack elements.
