CVE-2014-7824 [LOW] DBus vulnerability
Title: DBus vulnerability
Summary: DBus could be made to stop responding under certain conditions.
It was discovered that DBus incorrectly handled a large number of file
descriptor messages. A local attacker could use this issue to cause DBus to
stop responding, resulting in a denial of service. (CVE-2014-7824)
Instructions: After a standard system update you need to reboot your computer to make all
the necessary changes.

CVE-2014-7824 [LOW] CVE-2014-7824 dbus: local denial of service via incomplete fix for CVE-2014-3636
CVE-2014-7824 dbus: local denial of service via incomplete fix for CVE-2014-3636
The patch issued by the D-Bus maintainers for CVE-2014-3636 was based on
incorrect reasoning, and does not fully prevent the attack described as
"CVE-2014-3636 part A", which is repeated below. Preventing that attack
requires raising the system dbus-daemon's RLIMIT_NOFILE (ulimit -n) to a
higher value.
To avoid propagating that higher limit to activatable system services,
it is desirable to start the system dbus-daemon as root so it can store
its previous limit, raise its limit, drop root privileges (which its
default configuration will do automatically), and restore the previous
limit before launching activatable services. Some operating system
distributions, such as anything using the upstream-supplied sys

CVE-2014-3636 dbus: denial of service by queuing or splitting file descriptors

CVE-2014-3636 [LOW] CVE-2014-3636 dbus: denial of service by queuing or splitting file descriptors
CVE-2014-3636 dbus: denial of service by queuing or splitting file descriptors
A denial of service flaw was reported in D-Bus's file descriptor passing. A local, malicious user could use this flaw to cause a denial of service (prevent new connections to the bus, or disconnect something from the bus) by queuing up a large number of file descriptors to send, or by splitting a message to allow more file descriptors than expected to be sent.
It is believed that versions 1.3.0 and later are affected.
