EulerOS 2.0 SP1 : dbus (EulerOS-SA-2016-1037)

medium Nessus Plugin ID 99800

Synopsis

The remote EulerOS host is missing multiple security updates.

Description

According to the versions of the dbus packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

 - D-BUS is a system for sending messages between applications. It is used both for the system-wide message bus service, and as a per-user-login-session messaging facility.

 - Security Fix(es)

 - dbus 1.3.0 before 1.6.22 and 1.8.x before 1.8.6, when running on Linux 2.6.37-rc4 or later, allows local users to cause a denial of service (system-bus disconnect of other services or applications) by sending a message containing a file descriptor, then exceeding the maximum recursion depth before the initial message is forwarded.(CVE-2014-3532)

 - 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)

 - 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)

 - 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)

 - 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)

 - 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)

 - 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)

 - 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)

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.

Solution

Update the affected dbus packages.
