LVM2 socket priviliege escalation
|lvm2-socket-privilege-escalation (60809)||High Risk|
LVM2 could allow a local attacker to gain elevated privileges on the system, caused by the use of an abstract socket for communication between lvm and clvmd. If clvmd is running, a local attacker could exploit this vulnerability to direct clvmd to perform elevated operations.
Upgrade to the latest version of LVM2 (2.02.72 or later), available from the LVM2 Web page. See References.

- CVE-2010-2526: The cluster logical volume manager daemon (clvmd) in lvm2-cluster in LVM2 before 2.02.72, as used in Red Hat Global File System (GFS) and other products, does not verify client credentials upon a socket connection, which allows local users to cause a denial of service (daemon exit or logical-volume change) or possibly have unspecified other impact via crafted control commands.
