Package : dbus
CVE ID : CVE-2019-12749
Debian Bug : 930375
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.
