Package : dbus
CVE ID : CVE-2014-3635 CVE-2014-3636 CVE-2014-3637 CVE-2014-3638
CVE-2014-3639
Alban Crequy and Simon McVittie discovered several vulnerabilities in
the D-Bus message daemon.
CVE-2014-3635
On 64-bit platforms, file descriptor passing could be abused by
local users to cause heap corruption in the dbus-daemon crash,
leading to a crash, or potentially to arbitrary code execution.
CVE-2014-3636
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-2014-3637
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-2014-3638
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-2014-3639
dbus-daemon did not properly reject malicious connections from
local users, resulting in a denial-of-service vulnerability.
For the stable distribution (wheezy), these problems have been fixed in
version 1.6.8-1+deb7u4.
For the unstable distribution (sid), these problems have been fixed in
version 1.8.8-1.
We recommend that you upgrade your dbus packages.
