"The remote Oracle Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the
ELSA-2023-7467 advisory.

  - 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. (CVE-2023-42669)

  - 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 acl_xattr is configured with acl_xattr:ignore system
    acls = yes. 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's permissions. (CVE-2023-4091)

  - 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. (CVE-2023-3961)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version
number.");
