Debian Security Advisory DSA-3161-1 security@debian.org
http://www.debian.org/security/ Salvatore Bonaccorso
February 11, 2015 http://www.debian.org/security/faq
- - -------------------------------------------------------------------------
Package : dbus
CVE ID : CVE-2015-0245
Debian Bug : 777545
Simon McVittie discovered a local denial of service flaw in dbus, an
asynchronous inter-process communication system. On systems with
systemd-style service activation, dbus-daemon does not prevent forged
ActivationFailure messages from non-root processes. A malicious local
user could use this flaw to trick dbus-daemon into thinking that systemd
failed to activate a system service, resulting in an error reply back to
the requester.
For the stable distribution (wheezy), this problem has been fixed in
version 1.6.8-1+deb7u6.
For the unstable distribution (sid), this problem has been fixed in
version 1.8.16-1.
We recommend that you upgrade your dbus packages.
