The remote NewStart CGSL host, running version MAIN 6.06, has dbus packages installed that are affected by multiple vulnerabilities:

  - dbus before 1.10.28, 1.12.x before 1.12.16, and 1.13.x before 1.13.12, as used in DBusServer in Canonical     Upstart in Ubuntu 14.04 (and in some, less common, uses of dbus-daemon), allows cookie spoofing because of     symlink mishandling in the reference implementation of DBUS_COOKIE_SHA1 in the libdbus library. (This only     affects the DBUS_COOKIE_SHA1 authentication mechanism.) A malicious client with write access to its own     home directory could manipulate a ~/.dbus-keyrings symlink to cause a DBusServer with a different uid to     read and write in unintended locations. In the worst case, this could result in the DBusServer reusing a     cookie that is known to the malicious client, and treating that cookie as evidence that a subsequent     client connection came from an attacker-chosen uid, allowing authentication bypass. (CVE-2019-12749)

  - libdbus 1.5.x and earlier, when used in setuid or other privileged programs in X.org and possibly other     products, allows local users to gain privileges and execute arbitrary code via the DBUS_SYSTEM_BUS_ADDRESS     environment variable. NOTE: libdbus maintainers state that this is a vulnerability in the applications     that do not cleanse environment variables, not in libdbus itself: we do not support use of libdbus in     setuid binaries that do not sanitize their environment before their first call into libdbus.
    (CVE-2012-3524)

  - Unspecified vulnerability in the match_rule_equal function in bus/signals.c in D-Bus before 1.0.2 allows     local applications to remove match rules for other applications and cause a denial of service (lost     process messages). (CVE-2006-6107)

  - dbus-daemon in D-Bus before 1.0.3, and 1.1.x before 1.1.20, recognizes send_interface attributes in allow     directives in the security policy only for fully qualified method calls, which allows local users to     bypass intended access restrictions via a method call with a NULL interface. (CVE-2008-0595)

  - The _dbus_validate_signature_with_reason function (dbus-marshal-validate.c) in D-Bus (aka DBus) before     1.2.14 uses incorrect logic to validate a basic type, which allows remote attackers to spoof a signature     via a crafted key. NOTE: this is due to an incorrect fix for CVE-2008-3834. (CVE-2009-1189)

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

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - The dbus-daemon in D-Bus 1.2.x through 1.4.x, 1.6.x before 1.6.20, and 1.8.x before 1.8.4, sends an     AccessDenied error to the service instead of a client when the client is prohibited from accessing the     service, which allows local users to cause a denial of service (initialization failure and exit) or     possibly conduct a side-channel attack via a D-Bus message to an inactive service. (CVE-2014-3477)

Note that Nessus relies on the presence of the package as reported by the vendor.

This updates fixes multiple (local) denial of services discovered by Alban Crequy and Simon McVittie.

CVE-2014-3477

Fix a denial of service (failure to obtain bus name) in newly-activated system services that not all users are allowed to access.

CVE-2014-3638

Reduce maximum number of pending replies per connection to avoid algorithmic complexity denial of service.

CVE-2014-3639

The daemon now limits the number of unauthenticated connection slots so that malicious processes cannot prevent new connections to the system bus.

    (CVE-2012-3524)

  - The _dbus_printf_string_upper_bound function in dbus/dbus-sysdeps-unix.c in D-Bus (aka DBus) 1.4.x before     1.4.26, 1.6.x before 1.6.12, and 1.7.x before 1.7.4 allows local users to cause a denial of service     (service crash) via a crafted message. (CVE-2013-2168)

  - The dbus-daemon in D-Bus 1.2.x through 1.4.x, 1.6.x before 1.6.20, and 1.8.x before 1.8.4, sends an     AccessDenied error to the service instead of a client when the client is prohibited from accessing the     service, which allows local users to cause a denial of service (initialization failure and exit) or     possibly conduct a side-channel attack via a D-Bus message to an inactive service. (CVE-2014-3477)

  - dbus 1.3.0 before 1.6.22 and 1.8.x before 1.8.6 allows local users to cause a denial of service     (disconnect) via a certain sequence of crafted messages that cause the dbus-daemon to forward a message     containing an invalid file descriptor. (CVE-2014-3533)

  - Off-by-one error in D-Bus 1.3.0 through 1.6.x before 1.6.24 and 1.8.x before 1.8.8, when running on a     64-bit system and the max_message_unix_fds limit is set to an odd number, allows local users to cause a     denial of service (dbus-daemon crash) or possibly execute arbitrary code by sending one more file     descriptor than the limit, which triggers a heap-based buffer overflow or an assertion failure.
    (CVE-2014-3635)

  - D-Bus 1.3.0 through 1.6.x before 1.6.24 and 1.8.x before 1.8.8 allows local users to (1) cause a denial of     service (prevention of new connections and connection drop) by queuing the maximum number of file     descriptors or (2) cause a denial of service (disconnect) via multiple messages that combine to have more     than the allowed number of file descriptors for a single sendmsg call. (CVE-2014-3636)

  - D-Bus 1.3.0 through 1.6.x before 1.6.24 and 1.8.x before 1.8.8 does not properly close connections for     processes that have terminated, which allows local users to cause a denial of service via a D-bus message     containing a D-Bus connection file descriptor. (CVE-2014-3637)

  - The bus_connections_check_reply function in config-parser.c in D-Bus before 1.6.24 and 1.8.x before 1.8.8     allows local users to cause a denial of service (CPU consumption) via a large number of method calls.
    (CVE-2014-3638)

  - The dbus-daemon in D-Bus before 1.6.24 and 1.8.x before 1.8.8 does not properly close old connections,     which allows local users to cause a denial of service (incomplete connection consumption and prevention of     new connections) via a large number of incomplete connections. (CVE-2014-3639)

  - D-Bus 1.3.0 through 1.6.x before 1.6.26, 1.8.x before 1.8.10, and 1.9.x before 1.9.2 allows local users to     cause a denial of service (prevention of new connections and connection drop) by queuing the maximum     number of file descriptors. NOTE: this vulnerability exists because of an incomplete fix for     CVE-2014-3636.1. (CVE-2014-7824)

  - D-Bus 1.4.x through 1.6.x before 1.6.30, 1.8.x before 1.8.16, and 1.9.x before 1.9.10 does not validate     the source of ActivationFailure signals, which allows local users to cause a denial of service (activation     failure error returned) by leveraging a race condition involving sending an ActivationFailure signal     before systemd responds. (CVE-2015-0245)

  - An issue was discovered in dbus >= 1.3.0 before 1.12.18. The DBusServer in libdbus, as used in dbus-     daemon, leaks file descriptors when a message exceeds the per-message file descriptor limit. A local     attacker with access to the D-Bus system bus or another system service's private AF_UNIX socket could use     this to make the system service reach its file descriptor limit, denying service to subsequent D-Bus     clients. (CVE-2020-12049)

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