Alpine: multiple dbus packages: security update to 1.12.16-r0

high Tenable Self-Hosted Container Security Plugin ID 423828

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - 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)
