The remote NewStart CGSL host, running version MAIN 6.02, has dbus packages installed that are affected by a vulnerability:

  - 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 this issue but has instead relied only on the application's self-reported version number.

According to the version of the dbus packages installed, the EulerOS Virtualization installation on the remote host is affected by the following vulnerability :

  - 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 Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

The version of AOS installed on the remote host is prior to 5.17.1.5. It is, therefore, affected by multiple vulnerabilities as referenced in the NXSA-AOS-5.17.1.5 advisory.

  - An issue was discovered in the Linux kernel before 4.14.11. A double free may be caused by the function     allocate_trace_buffer in the file kernel/trace/trace.c. (CVE-2017-18595)

  - In the Linux kernel 5.4.0-rc2, there is a use-after-free (read) in the __blk_add_trace function in     kernel/trace/blktrace.c (which is used to fill out a blk_io_trace structure and place it in a per-cpu sub-     buffer). (CVE-2019-19768)

  - A NULL pointer dereference flaw was found in the Linux kernel's SELinux subsystem in versions before 5.7.
    This flaw occurs while importing the Commercial IP Security Option (CIPSO) protocol's category bitmap into     the SELinux extensible bitmap via the' ebitmap_netlbl_import' routine. While processing the CIPSO     restricted bitmap tag in the 'cipso_v4_parsetag_rbm' routine, it sets the security attribute to indicate     that the category bitmap is present, even if it has not been allocated. This issue leads to a NULL pointer     dereference issue while importing the same category bitmap into SELinux. This flaw allows a remote network     user to crash the system kernel, resulting in a denial of service. (CVE-2020-10711)

  - 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)

    (CVE-2020-14621)

  - ntpd in ntp before 4.2.8p14 and 4.3.x before 4.3.100 allows an off-path attacker to block unauthenticated     synchronization via a server mode packet with a spoofed source IP address, because transmissions are     rescheduled even when a packet lacks a valid origin timestamp. (CVE-2020-11868)

  - ntpd in ntp before 4.2.8p14 and 4.3.x before 4.3.100 allows remote attackers to cause a denial of service     (daemon exit or system time change) by predicting transmit timestamps for use in spoofed packets. The     victim must be relying on unauthenticated IPv4 time sources. There must be an off-path attacker who can     query time from the victim's ntpd instance. (CVE-2020-13817)

  - The VFIO PCI driver in the Linux kernel through 5.6.13 mishandles attempts to access disabled memory     space. (CVE-2020-12888)

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

The remote NewStart CGSL host, running version MAIN 6.02, has dbus packages installed that are affected by multiple vulnerabilities:

  - 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)

  - 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)

  - 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.
