Debian DLA-2064-1 : ldm security update

high Nessus Plugin ID 132776

Synopsis

The remote Debian host is missing a security update.

Description

It was discovered that a hook script of ldm, the display manager for the Linux Terminal Server Project incorrectly parsed responses from an SSH server which could result in local root privilege escalation.

For Debian 8 'Jessie', this issue has been fixed in ldm version 2:2.2.15-2+deb8u1.

We recommend that you upgrade your ldm 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 ldm, and ldm-server packages.
