Debian DLA-2006-1 : libxdmcp security update

medium Nessus Plugin ID 131291

Language:

Synopsis

The remote Debian host is missing a security update.

Description

It has been found, that libxdmcp, an X11 Display Manager Control Protocol library, uses weak entropy to generate keys.

Using arc4random_buf() from libbsd should avoid this flaw.

For Debian 8 'Jessie', this problem has been fixed in version 1:1.1.1-1+deb8u1.

We recommend that you upgrade your libxdmcp packages.

NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Upgrade the affected packages.
