CVSS Base Vector:
AV:L/AC:L/Au:N/C:P/I:P/A:N

Summary:
The remote host is missing an update for the 'dbus' Linux Distribution Package(s) announced via the DSA-4462-1 advisory.

Detection Method:
Checks if a vulnerable Linux Distribution Package version is present on the target host.

Technical Details:
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.

Affected Versions:
'dbus' Linux Distribution Package(s) on Debian Linux.

Recommendations:
For the stable distribution (stretch), this problem has been fixed in version 1.10.28-0+deb9u1. We recommend that you upgrade your dbus Linux Distribution Packages.

Solution Type:
Vendor Patch

Detection Type:
Linux Distribution Package
