Scientific Linux Security Update : lvm2-cluster,lvm2 for SL5
medium Nessus Plugin ID 60824
Language:
Synopsis
The remote Scientific Linux host is missing one or more security updates.Description
It was discovered that the cluster logical volume manager daemon (clvmd) did not verify the credentials of clients connecting to its control UNIX abstract socket, allowing local, unprivileged users to send control commands that were intended to only be available to the privileged root user. This could allow a local, unprivileged user to cause clvmd to exit, or request clvmd to activate, deactivate, or reload any logical volume on the local system or another system in the cluster. (CVE-2010-2526)Note: This update changes clvmd to use a pathname-based socket rather than an abstract socket. As such, the lvm2 update 2010:0569, which changes LVM to also use this pathname-based socket, must also be installed for LVM to be able to communicate with the updated clvmd.
All lvm2-cluster users should upgrade to this updated package, which contains a backported patch to correct this issue. After installing the updated package, clvmd must be restarted for the update to take effect.
