Debian DSA-2095-1 : lvm2 - insecure communication protocol

medium Nessus Plugin ID 48895

Language:

New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.

Synopsis

The remote Debian host is missing a security-related update.

Description

Alasdair Kergon discovered that the cluster logical volume manager daemon (clvmd) in LVM2, The Linux Logical Volume Manager, does not verify client credentials upon a socket connection, which allows local users to cause a denial of service.

Solution

Upgrade the lvm2 package.

For the stable distribution (lenny), this problem has been fixed in version 2.02.39-8.
