Updated dbus packages fixes the following security issues:

Alban Crequy and Simon McVittie discovered several vulnerabilities
in the D-Bus message daemon:

On 64-bit platforms, file descriptor passing could be abused by local
users to cause heap corruption in dbus-daemon, leading to a crash,
or potentially to arbitrary code execution (CVE-2014-3635).

A denial-of-service vulnerability in dbus-daemon allowed local
attackers to prevent new connections to dbus-daemon, or disconnect
existing clients, by exhausting descriptor limits (CVE-2014-3636).

Malicious local users could create D-Bus connections to dbus-daemon
which could not be terminated by killing the participating processes,
resulting in a denial-of-service vulnerability (CVE-2014-3637).

dbus-daemon suffered from a denial-of-service vulnerability in the
code which tracks which messages expect a reply, allowing local
attackers to reduce the performance of dbus-daemon (CVE-2014-3638).

dbus-daemon did not properly reject malicious connections from local
users, resulting in a denial-of-service vulnerability (CVE-2014-3639).

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.

By queuing up the maximum allowed number of fds, a malicious sender
could reach the system dbus-daemon’s RLIMIT_NOFILE (ulimit -n,
typically 1024 on Linux). This would act as a denial of service in
two ways:

* new clients would be unable to connect to the dbus-daemon
* when receiving a subsequent message from a non-malicious client
that contained a fd, dbus-daemon would receive the MSG_CTRUNC flag,
indicating that the list of fds was truncated; kernel fd-passing APIs
do not provide any way to recover from that, so dbus-daemon responds
to MSG_CTRUNC by disconnecting the sender, causing denial of service
to that sender.

This update also resolves the CVE-2014-7824 security vulnerability.

Updated curl packages fix security vulnerability:

Symeon Paraschoudis discovered that the curl_easy_duphandle() function
in cURL has a bug that can lead to libcurl eventually sending off
sensitive data that was not intended for sending, while performing
a HTTP POST operation. This bug requires CURLOPT_COPYPOSTFIELDS and
curl_easy_duphandle() to be used in that order, and then the duplicate
handle must be used to perform the HTTP POST. The curl command line
tool is not affected by this problem as it does not use this sequence
(CVE-2014-3707).
