Detail
Joe Vennix discovered an authentication bypass vulnerability in dbus, an asynchronous inter-process communication system. The implementation of the DBUS_COOKIE_SHA1 authentication mechanism was susceptible to a symbolic link attack. A local attacker could take advantage of this flaw to bypass authentication and connect to a DBusServer with elevated privileges. The standard system and session dbus-daemons in their default configuration are not affected by this vulnerability. The vulnerability was addressed by upgrading dbus to a new upstream version 1.10.28 which includes additional fixes. For the stable distribution (stretch), this problem has been fixed in version 1.10.28-0+deb9u1. We recommend that you upgrade your dbus packages. For the detailed security status of dbus please refer to its security tracker page at: https://security-tracker.debian.org/tracker/dbus |
