SUSE SLES11 Security Update : dbus-1 (SUSE-SU-2019:14111-1)

high Nessus Plugin ID 150575

Language:

Synopsis

The remote SUSE host is missing a security update.

Description

The remote SUSE Linux SLES11 host has packages installed that are affected by a vulnerability as referenced in the SUSE- SU-2019:14111-1 advisory.

- dbus before 1.10.28, 1.12.x before 1.12.16, and 1.13.x before 1.13.12, as used in DBusServer in Canonical Upstart in Ubuntu 14.04 (and in some, less common, uses of dbus-daemon), allows cookie spoofing because of symlink mishandling in the reference implementation of DBUS_COOKIE_SHA1 in the libdbus library. (This only affects the DBUS_COOKIE_SHA1 authentication mechanism.) A malicious client with write access to its own home directory could manipulate a ~/.dbus-keyrings symlink to cause a DBusServer with a different uid to read and write in unintended locations. In the worst case, this could result in the DBusServer reusing a cookie that is known to the malicious client, and treating that cookie as evidence that a subsequent client connection came from an attacker-chosen uid, allowing authentication bypass. (CVE-2019-12749)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Update the affected dbus-1, dbus-1-32bit and / or dbus-1-x11 packages.
