medium Nessus Plugin ID 48895

Language:

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.
