Security update for dbus-1
SUSE Security Update: Security update for dbus-1
This update fixes the following security issue:
- CVE-2015-0245: Do not allow non-uid-0 processes to send forged
ActivationFailure messages. On Linux systems with systemd activation,
this would allow a local denial of service (bnc#916343).
These additional security hardenings are included:
- Do not allow calls to UpdateActivationEnvironment from uids
other than the uid of the dbus-daemon. If a system service installs
unsafe security policy rules that allow arbitrary method calls (such as
CVE-2014-8148) then this prevents memory consumption and possible
privilege escalation via UpdateActivationEnvironment.
- Do not allow calls to UpdateActivationEnvironment or the Stats interface
on object paths other than /org/freedesktop/DBus. Some system services
install unsafe security policy rules that allow arbitrary method calls
to any destination, method and interface with a specified object path.
